Definitions

  • the invention is in the field of washing and cleaning agents, in particular enzyme-containing washing and cleaning agents, and relates to the use of a dispersin or a dispersin-containing agent for preventing and/or reducing bad smells on surfaces, in particular household surfaces, preferably in washing machines or dishwashers, pump sumps, storage containers, water reservoirs, washing drums, rinsing chambers, washing or sink basins, toilet bowls, cisterns, toilet rims, siphons, water pipes and/or lines, water inlets and/or outlets, and/or for preventing and/or reducing and/or removing microbially caused deposits on surfaces, in particular household surfaces, preferably in washing machines or dishwashers, pump sumps, storage containers, water reservoirs, washing drums, rinsing chambers, washing or sink basins, toilet bowls, cisterns, toilet rims, siphons, water pipes and/or lines, water inlets and/or outlets, and/or for improving the hygiene of surfaces, in particular household surfaces,
  • enzymes in detergents have been established in the state of the art for decades. They serve to expand the performance spectrum of the agents in question according to their special activities. These include in particular hydrolytic enzymes such as proteases, amylases, lipases and cellulases. The first three mentioned hydrolyze proteins, starch and fats and thus contribute directly to the removal of dirt. Cellulases are used in textile detergents in particular because of their effect on fabrics.
  • Another group of detergent enzymes are oxidative enzymes, in particular oxidases, which, if necessary in conjunction with other components, preferably serve to bleach soiling and/or to generate the bleaching agents in situ.
  • bad smell means a smell that is not desired on surfaces, in particular household surfaces, dishes, textiles and cleaned objects, in particular cleaned textiles and cleaned dishes.
  • the cleaned object should smell fresh and clean without a bad smell clinging to it.
  • a wide variety of causes can cause an unpleasant smell, so-called bad smell, on surfaces, in particular household surfaces, as well as on washed textiles and/or cleaned hard surfaces, in particular dishes.
  • household surface means, for example, surfaces in washing machines or dishwashers, pump sumps, storage containers, water reservoirs, washing drums, rinsing chambers, wash basins or sinks, toilet bowls, cisterns, toilet rims, siphons, water pipes and/or lines, water inlets and/or outlets.
  • Bad smells are known to be a problem, especially with textiles and washing machines. But bad smells can also be found in dishwashers.
  • microbial bio-deposits i.e. microbial bad odors resulting from microbial bio-deposits.
  • Another example of unpleasant odors is sweat or body odor that adheres to an object that has come into contact with people or animals.
  • Bad smells are not only found in the washing machine, but also on freshly washed, still damp laundry, as well as on dry laundry, and on numerous other surfaces, especially household surfaces that come into contact with dirty objects and/or water, especially used water, and/or washing/cleaning solution, such as surfaces in washing machines or dishwashers, pump sumps, storage containers, water reservoirs, washing drums, rinsing chambers, wash basins or sinks, toilet bowls, cisterns, toilet rims, siphons, water pipes and/or lines, water inlets and/or outlets.
  • Deposits, bio-deposits, body soils and the like not only lead to bad smells, but can also become visible as soiling on textiles and/or surfaces, in particular household surfaces, such as surfaces in washing machines or dishwashers, pump sumps, storage containers, water reservoirs, washing drums, rinsing chambers, wash basins or sinks, toilet bowls, cisterns, toilet rims, siphons, water pipes and/or lines, water inlets and/or outlets, e.g. in the form of deposits, smears, encrustations, yellowing, armpit stains and greying.
  • Bio-deposits and the like due to their typically adhesive texture, also enable other bad smell and/or dirt particles to adhere. However, bad smells can also be present before the microbial deposits lead to visible soiling.
  • biodeposit does not only mean biofilms in the narrow sense, such as microbial deposits, biofilms or the like, which can be formed by any microorganisms whose cells adhere to each other and/or to a surface, e.g. to textiles, tableware or a hard surface or another type of surface, but also more generally any biodeposits, biosoils, biological deposits or the like including, but not limited to, degradation and deposition products of microorganisms that adhere to a surface, e.g. to textiles, tableware or a hard surface or another type of surface.
  • EPS extracellular polymeric substance
  • Biofilm EPS is a polymeric conglomerate that generally consists of extracellular DNA, proteins and polysaccharides. Biofilms can form on living or non-living surfaces.
  • the microbial cells that grow in a biofilm differ physiologically from the planktonic cells of the same organism, which in contrast are single cells that float or can swim in a liquid medium.
  • Bacterial cells living in a biofilm usually have significantly different properties than planktonic bacterial cells of the same species, because the dense and protected environment of the film allows them to cooperate and interact in different ways.
  • One advantage of this environment for the microorganisms is increased resistance to detergents and antibiotics, because the dense extracellular matrix and outer cell layer protect the interior of the community.
  • Biofilm-producing bacteria on textiles include, for example, the following species: Acinetobacter sp., Aeromicrobium sp., Brevundimonas sp., Microbacterium sp., Micrococcus luteus, Pseudomonas sp., Staphylococcus epidermidis and Stenotrophomonas sp.
  • Biofilm-forming bacteria found on hard surfaces include the following species: Acinetobacter sp., Aeromicrobium sp., Brevundimonas sp., Microbacterium sp., Micrococcus luteus, Pseudomonas sp, Staphylococcus epidermidis, Staphylococcus aureus and Stenotrophomonas sp.
  • EP 3892708, WO 2021/122117, WO 2021/122118, WO 2021/122120, WO 2021/122121 and WO 2022/008387 describe washing and cleaning agents containing dispersin and enzymes. It has also been described that dispersin can degrade biofilm and EPS, for example.
  • fragrances have side effects such as allergenic properties that can manifest themselves in the form of skin rashes.
  • fragrances have been increasingly used in the form of fragrance microcapsules, although it is known that microcapsules are considered microplastics and are therefore potentially harmful to the environment.
  • fragrances are expensive and add to the overall cost of detergents and cleaning agents.
  • the dispersin according to the invention reliably removes microbially caused bad odors as well as microbially caused deposits, bio-deposits and the like from surfaces, in particular household surfaces, such as surfaces in washing machines or dishwashers, pump sumps, storage containers, water reservoirs, washing drums, rinsing chambers, wash basins or sinks, toilet bowls, cisterns, toilet rims, siphons, water pipes and/or lines, water inlets and/or outlets.

  • ß-1,6-N-acetylglucosamnidase activity is synonymous with “hexosaminidase activity” and/or “dispersin activity” and is determined as follows: To determine dispersin activity, 35 ⁇ l of dispersin assay solution (45 mM citrate buffer pH 5 with 0.5 mg/ml p-nitrophenyl-N-acetyl-ß-D-glucosaminide) is added to a microtiter plate containing 5 ⁇ l of sample solution per well. The microtiter plate is incubated for 3 hours at room temperature. After incubation, 40 ⁇ l of stop solution (0.4 M Na2CO3) is added and the absorbance is measured at 405 nm. The activity values obtained are corrected by subtracting the absorbance measurement obtained for a reference without dispersin in order to eliminate background noise. From this, the residual activity (RA) for the respective dispersin variant can be calculated in comparison to a reference dispersin.

In this case, a single or multiple enzyme molecule(s) can be separated from the other components of the agent by a structure surrounding them. Such a separating structure can be created by, but is not limited to, vesicles, such as a micelle or a liposome.

  • the enzymes described herein have the sequence of the respective reference sequence with the exception of the explicitly mentioned substitutions, i.e. are 100% identical to the respective reference sequence apart from the substituted positions.
  • sequence comparison The identity of nucleic acid or amino acid sequences is determined by sequence comparison. This sequence comparison is based on the state-of-the-art and commonly used BLAST algorithm (see e.g. Altschul et al., Basic local alignment search tool, J. Mol. Biol., 1990, 215: 403-410, and Altschul et al., Gapped BLAST and PSI-BLAST: a new generation of protein database search programs, Nucleic Acids Res., 1997, 25: 3389-3402) and is carried out in principle by assigning similar sequences of nucleotides or amino acids in the nucleic acid or amino acid sequences to one another. A tabular assignment of the relevant positions is referred to as an alignment.
  • Sequence comparisons are created using computer programs. Commonly used programs include the Clustal series (see e.g. Chenna et al., Multiple sequence alignment with the Clustal series of programs, Nucleic Acid Res., 2003, 31 : 3497-3500), T-Coffee (see e.g. Notredame et al., T-Coffee: A novel method for multiple sequence alignments, J. Mol. Biol., 2000, 302: 205-217) or programs based on these programs or algorithms.
  • Sequence comparisons can also be carried out using the computer program Vector NTI® Suite 10.3 (Invitrogen Corporation, 1600 Faraday Avenue, Carlsbad, California, USA) with the specified standard parameters, whose AlignX module for sequence comparisons is based on ClustalW, or Clone Manager 10 (use of the BLOSUM 62 scoring matrix for sequence alignment at the amino acid level). Unless otherwise stated, sequence identity reported herein is determined using the BLAST algorithm.
  • Such a comparison also allows a statement to be made about the similarity of the sequences being compared to one another. This is usually expressed in percent identity, i.e. the proportion of identical nucleotides or amino acid residues at the same positions or positions that correspond to one another in an alignment.
  • the broader term homology includes conserved amino acid exchanges in amino acid sequences, i.e. amino acids with similar chemical activity, since these usually perform similar chemical activities within the protein. Therefore, the similarity of the sequences being compared can also be expressed as percent homology or percent similarity. Identity and/or homology statements can be made for entire polypeptides or genes or just for individual regions. Homologous or identical regions of different nucleic acid or amino acid sequences are therefore defined by similarities in the sequences.
  • Such regions often have identical functions. They can be small and contain only a few nucleotides or amino acids. Such small regions often perform essential functions for the overall activity of the protein. It may therefore be useful to relate sequence matches only to individual, possibly small regions. Unless otherwise stated, identity or homology statements in the present application refer to the total length of the respective nucleic acid or amino acid sequence specified.
  • an amino acid position corresponds to a numerically designated position in SEQ ID NO:1 therefore means that the corresponding position is assigned to the numerically designated position in SEQ ID NO:1 in an alignment as defined above.
  • amino acid exchanges For the description of substitutions that affect exactly one amino acid position (amino acid exchanges), the following convention is used: first, the naturally occurring amino acid is designated in the form of the internationally used one-letter code, then follows the corresponding sequence position and finally the inserted amino acid. Multiple or alternative exchanges within the same polypeptide chain are separated from one another by slashes. "130D/V" thus means that position 130 is mutated to D or V. In the case of insertions, additional amino acids are named after the sequence position. In the case of deletions, the missing amino acid is replaced by a symbol, for example an asterisk or a dash, or an A is indicated in front of the corresponding position.
  • P9T describes the substitution of proline at position 9 by threonine
  • P9TH the insertion of histidine after the amino acid threonine at position 9

Des Weiteren betrifft die Erfindung entsprechende Mittel und Verfahren. The invention is in the field of washing and cleaning agents, in particular enzyme-containing washing and cleaning agents, and relates to the use of a dispersin or a dispersin-containing agent for preventing and/or reducing bad smells on surfaces, in particular household surfaces, preferably in washing machines or dishwashers, pump sumps, storage containers, water reservoirs, washing drums, rinsing chambers, washing or sink basins, toilet bowls, cisterns, toilet rims, siphons, water pipes and/or lines, water inlets and/or outlets, and/or for preventing and/or reducing and/or removing microbially caused deposits on surfaces, in particular household surfaces, preferably in washing machines or dishwashers, pump sumps, storage containers, water reservoirs, washing drums, rinsing chambers, washing or sink basins, toilet bowls, cisterns, toilet rims, siphons, water pipes and/or lines, water inlets and/or outlets, and/or for improving the hygiene of surfaces, in particular household surfaces, preferably in washing machines or dishwashers, pump sumps, storage containers, water reservoirs, washing drums, rinsing chambers, wash basins or sinks, toilet bowls, cisterns, toilet rims, siphons, water pipes and/or lines, water inlets and/or outlets. The invention further relates to corresponding means and methods.
Der Einsatz von Enzymen in Waschmitteln ist seit Jahrzehnten im Stand der Technik etabliert. Sie dienen dazu, das Leistungsspektrum der betreffenden Mittel entsprechend ihren speziellen Aktivitäten zu erweitern. Hierzu gehören insbesondere hydrolytische Enzyme wie Proteasen, Amylasen, Lipasen und Cellulasen. Die ersten drei genannten hydrolysieren Proteine, Stärke und Fette und tragen somit unmittelbar zur Schmutzentfernung bei. Cellulasen werden in Textilwaschmitteln insbesondere wegen ihrer Gewebewirkung eingesetzt. Eine weitere Gruppe von Waschmittelenzymen sind oxidative Enzyme, insbesondere Oxidasen, die ggf. im Zusammenspiel mit anderen Komponenten vorzugsweise dazu dienen, Anschmutzungen zu bleichen und/oder die bleichenden Agentien in situ zu erzeugen. Neben diesen Enzymen, die einer fortwährenden Optimierung unterworfen sind, werden laufend weitere Enzyme für den Einsatz in Waschmitteln bereitgestellt, um insbesondere spezielle Anschmutzungen optimal angehen zu können, wie z.B. Pektinasen, Pektatlysasen, Xanthanasen, ß-Glucanasen, Mannanasen, Dispersine und dergleichen, zur Hydrolyse insbesondere spezieller pflanzlicher Polymere. Generell sind nur ausgewählte Enzyme für den Einsatz in flüssigen Tensid-haltigen Zubereitungen überhaupt geeignet. Viele Enzyme zeigen in derartigen Zubereitungen keine ausreichende katalytische Leistung. Für die Anwendung von Enzymen in Reinigungsmitteln ist daher eine hohe katalytische Aktivität unter Bedingungen wie sie sich während eines Waschgangs darstellen und eine hohe Lagerstabilität besonders wünschenswert. An die Konfektions- und Angebotsformen von Wasch- und Reinigungsmittel werden sich kontinuierlich ändernde Anforderungen gestellt. Ein Hauptaugenmerk liegt dabei seit geraumer Zeit auf der bequemen Dosierung von Wasch- und Reinigungsmitteln durch den Verbraucher und der Vereinfachung der zur Durchführung eines Wasch- oder Reinigungsverfahren notwendigen Arbeitsschritte. Eine technische Lösung bieten vorportionierte Wasch- oder Reinigungsmittel, beispielsweise Folienbeutel mit einer oder mehreren Aufnahmekammern für feste und/oder flüssige Wasch- und Reinigungsmittel. Ein für die Herstellung dieser Folienbeutel relevanter Trend, ist die Miniaturisierung dieser Folienbeutel. Hintergrund dieser Entwicklung sind neben einer höheren Verbraucherakzeptanz aufgrund vereinfachter Handhabung insbesondere Nachhaltigkeitsaspekte, beispielsweise in Bezug auf Transportvolumina und -kosten und die Menge der eingesetzten Verpackungsmittel. Die Aufkonzentration moderner Wasch- und Reinigungsmittel setzt eine fortschreitende Optimierung bestehender Rezepturen und die Entwicklung neuer, leistungsfähigerer Rezepturen voraus. Ein Ziel dieser Entwicklungen, bei denen in der Regel auf bekannte wasch- und reinigungsaktive Wirkstoffe zurückgegriffen wird, ist es, bei gleichbleibender oder verringerter Dosiermenge eine Wasch- oder Reinigungsleistungssteigerung der Rezepturen zu erreichen. The use of enzymes in detergents has been established in the state of the art for decades. They serve to expand the performance spectrum of the agents in question according to their special activities. These include in particular hydrolytic enzymes such as proteases, amylases, lipases and cellulases. The first three mentioned hydrolyze proteins, starch and fats and thus contribute directly to the removal of dirt. Cellulases are used in textile detergents in particular because of their effect on fabrics. Another group of detergent enzymes are oxidative enzymes, in particular oxidases, which, if necessary in conjunction with other components, preferably serve to bleach soiling and/or to generate the bleaching agents in situ. In addition to these enzymes, which are subject to continuous optimization, other enzymes are constantly being made available for use in detergents in order to be able to optimally tackle special types of soiling, such as pectinases, pectate lysases, xanthanases, ß-glucanases, mannanases, dispersins and the like, in particular for the hydrolysis of special plant polymers. In general, only selected enzymes are suitable for use in liquid surfactant-containing preparations. Many enzymes do not show sufficient catalytic performance in such preparations. For the use of enzymes in cleaning agents, a high catalytic activity under conditions such as those encountered during a wash cycle and a high storage stability are therefore particularly desirable. The packaging and supply of detergents and cleaning agents are subject to constantly changing requirements. For some time now, the main focus has been on the convenient dosing of detergents and cleaning agents by the consumer and the simplification of the work steps required to carry out a washing or cleaning process. Pre-portioned detergents or cleaning agents, for example film bags with one or more receiving chambers for solid and/or liquid detergents and cleaning agents, offer a technical solution. A relevant trend for the production of these film bags is the miniaturization of these film bags. In addition to greater consumer acceptance due to simplified handling, the background to this development is particularly sustainability aspects, for example in relation to transport volumes and costs and the amount of packaging used. The concentration of modern detergents and cleaning agents requires a progressive optimization of existing recipes and the development of new, more efficient recipes. One aim of these developments, which generally rely on known washing and cleaning active ingredients, is to achieve an increase in the washing or cleaning performance of the formulations while maintaining or reducing the dosage.
Das wichtigste Kriterium beim Reinigen von Textilien und/oder harten Oberflächen ist die Reinigungsleistung an verschiedensten Anschmutzungen. Auch wenn die Reinigungsleistung der heutzutage eingesetzten Wasch- und Reinigungsmittel generell hoch ist, stellt sich, auch aufgrund des generellen Trends vermehrt Niedrigtemperatur-Programme zu verwenden sowie durch den Trend zur Kompaktierung der Rezepturen (insbesondere bei vorportionierten Verwendungsformen), allerdings das Problem, dass viele der üblichen Wasch- und Reinigungsmittelrezepturen eine unzureichende Reinigungsleistung, insbesondere an hartnäckigen Anschmutzungen, aufweisen. Eine solche unzureichende Reinigungsleistung führen beim Verbraucher zu Unzufriedenheit und dazu, dass solche Anschmutzungen vom Verbraucher vorbehandelt werden, was wiederum den Wasser- und Energieverbrauch erhöht. The most important criterion when cleaning textiles and/or hard surfaces is the cleaning performance on a wide range of soiling. Even though the cleaning performance of the detergents and cleaning agents used today is generally high, the problem is that many of the usual detergent and cleaning agent formulations have insufficient cleaning performance, especially on stubborn soiling, due to the general trend towards using more low-temperature programs and the trend towards compacting the formulations (particularly in pre-portioned forms of use). Such insufficient cleaning performance leads to dissatisfaction among consumers and to consumers pre-treating such soiling, which in turn increases water and energy consumption.
Mit dem Begriff "Schlechtgeruch", wie hierin verwendet, ist ein Geruch gemeint, der auf Oberflächen, insbesondere Haushaltsoberflächen, Geschirr, Textilien und gereinigten Gegenständen, insbesondere gereinigte Textilien und gereinigtes Geschirr, nicht erwünscht ist. Der gereinigte Gegenstand sollte frisch und sauber riechen, ohne dass ihm ein Schlechtgeruch anhaftet. Verschiedenste Ursachen können auf Oberflächen, insbesondere Haushaltsoberflächen, sowie auf gewaschenen Textilien und/oder gereinigten harten Oberflächen, insbesondere Geschirr, einen unangenehmen Geruch, sog. Schlechtgeruch, verursachen. Der Begriff "Haushaltsoberfläche", wie hierin verwendet, meint z.B. Oberflächen in Wasch- oder Geschirrspülmaschinen, Pumpensümpfen, Vorrats be hä Item, Wasserreservoir, Waschtrommel, Spülkammern, Wasch- oder Spülbecken, Toilettenbecken, Spülkasten, WC-Rand, Siphons, Wasserrohren und/oder -leitungen, Wasserzu- und/oder -abläufen. Schlechtgeruch ist insbesondere bei Textilien und Waschmaschinen als Problem bekannt. Aber auch in der Geschirrspülmaschine findet sich Schlechtgeruch. Betroffen sind alle Bauteile, die mit verschmutzten Gegenständen und/oder Wasser, insbesondere gebrauchtem Wasser, und/oder Wasch-/Reinigungslauge in Berührung kommen, wie z.B. Oberflächen in Wasch- oder Geschirrspülmaschinen, Pumpensümpfen, Vorrats be hä Item, Wasserreservoir, Waschtrommel, Spülkammern, Wasch- oder Spülbecken, Toilettenbecken, Spülkasten, WC-Rand, Siphons, Wasserrohren und/oder -leitungen, Wasserzu- und/oder -abläufen. Eine, wenn nicht die häufigste, Ursache hierfür sind organischer Natur, wie z.B. Sebum, Körperschmutz (body soils; z.B. Körperöle, abgestorbene Hautschuppen und Schweiß), Zellrückstände, Nahrungsmittelreste, Körperausscheidungen, Biofilme und extrazelluläre polymere Substanzen (EPS; z.B. extrazelluläre polymere Saccharide). Hierbei hervorzuheben sind insbesondere die mikrobiell bedingten Biobeläge, d.h. mikrobiell bedingter Schlechtgeruch in Folge von mikrobiell bedingten Biobelägen. Ein weiteres Beispiel für unangenehme Gerüche ist Schweiß oder Körpergeruch, der an einem Gegenstand anhaftet, der mit Menschen oder Tieren in Berührung gekommen ist. Schlechtgeruch findet sich nicht nur in der Waschmaschine, sondern auch auf der frisch gewaschenen, noch feuchten Wäsche, sowie auch auf der trockenen Wäsche, sowie auf zahlreichen weiteren Oberflächen, insbesondere Haushaltsoberflächen, die mit verschmutzten Gegenständen und/oder Wasser, insbesondere gebrauchtem Wasser, und/oder Wasch-/Reinigungslauge in Berührung kommen, wie z.B. Oberflächen in Wasch- oder Geschirrspülmaschinen, Pumpensümpfen, Vorrats be hä Item, Wasserreservoir, Waschtrommel, Spülkammern, Wasch- oder Spülbecken, Toilettenbecken, Spülkasten, WC-Rand, Siphons, Wasserrohren und/oder -leitungen, Wasserzu- und/oder -abläufen. Ablagerungen, Biobeläge, Body soils und dergleichen führen jedoch nicht nur zu Schlechtgeruch, sondern können auch als Anschmutzungen auf Textilien und/oder Oberflächen, insbesondere Haushaltsoberflächen, wie z.B. Oberflächen in Wasch- oder Geschirrspülmaschinen, Pumpensümpfen, Vorrats be hä Item, Wasserreservoir, Waschtrommel, Spülkammern, Wasch- oder Spülbecken, Toilettenbecken, Spülkasten, WC-Rand, Siphons, Wasserrohren und/oder -leitungen, Wasserzu- und/oder -abläufen, Sichtbarwerden, z.B. in Form von Belägen, Schmier, Ankrustungen, Vergilbungen, Achselflecken und Vergrauungen. Biobeläge und dergleichen ermöglichen durch ihre typischerweise adhäsive Textur auch das Anhaften weiterer Schlechtgeruchs- und/oder Schmutzpartikel. Schlechtgeruch kann jedoch auch schon vorhanden sein, bevor die mikrobiell bedingten Ablagerungen zu sichtbaren Verschmutzungen führen. The term "bad smell" as used herein means a smell that is not desired on surfaces, in particular household surfaces, dishes, textiles and cleaned objects, in particular cleaned textiles and cleaned dishes. The cleaned object should smell fresh and clean without a bad smell clinging to it. A wide variety of causes can cause an unpleasant smell, so-called bad smell, on surfaces, in particular household surfaces, as well as on washed textiles and/or cleaned hard surfaces, in particular dishes. The term "household surface" as used herein means, for example, surfaces in washing machines or dishwashers, pump sumps, storage containers, water reservoirs, washing drums, rinsing chambers, wash basins or sinks, toilet bowls, cisterns, toilet rims, siphons, water pipes and/or lines, water inlets and/or outlets. Bad smells are known to be a problem, especially with textiles and washing machines. But bad smells can also be found in dishwashers. This affects all components that come into contact with dirty objects and/or water, especially used water, and/or washing/cleaning solutions, such as surfaces in washing or Dishwashers, pump sumps, storage containers, items, water reservoirs, washing drums, rinsing chambers, wash basins or sinks, toilet bowls, cisterns, toilet rims, siphons, water pipes and/or lines, water inlets and/or outlets. One, if not the most common, cause of this is of an organic nature, such as sebum, body soils (e.g. body oils, dead skin cells and sweat), cell residues, food remains, bodily excretions, biofilms and extracellular polymeric substances (EPS; e.g. extracellular polymeric saccharides). Of particular note here are microbial bio-deposits, i.e. microbial bad odors resulting from microbial bio-deposits. Another example of unpleasant odors is sweat or body odor that adheres to an object that has come into contact with people or animals. Bad smells are not only found in the washing machine, but also on freshly washed, still damp laundry, as well as on dry laundry, and on numerous other surfaces, especially household surfaces that come into contact with dirty objects and/or water, especially used water, and/or washing/cleaning solution, such as surfaces in washing machines or dishwashers, pump sumps, storage containers, water reservoirs, washing drums, rinsing chambers, wash basins or sinks, toilet bowls, cisterns, toilet rims, siphons, water pipes and/or lines, water inlets and/or outlets. Deposits, bio-deposits, body soils and the like not only lead to bad smells, but can also become visible as soiling on textiles and/or surfaces, in particular household surfaces, such as surfaces in washing machines or dishwashers, pump sumps, storage containers, water reservoirs, washing drums, rinsing chambers, wash basins or sinks, toilet bowls, cisterns, toilet rims, siphons, water pipes and/or lines, water inlets and/or outlets, e.g. in the form of deposits, smears, encrustations, yellowing, armpit stains and greying. Bio-deposits and the like, due to their typically adhesive texture, also enable other bad smell and/or dirt particles to adhere. However, bad smells can also be present before the microbial deposits lead to visible soiling.
Der Begriff "Biobelag" wie hierin verwendet, meint nicht nur Biofilme im engeren Sinne, wie mikrobiell bedingte Ablagerungen, Biofilme oder dergleichen, die von jeglichen Mikroorganismen gebildet werden können, deren Zellen aneinander und/oder an einer Oberfläche anhaften, z.B. an Textilien, Geschirr oder einer harten Oberfläche oder einer anderen Art von Oberfläche, sondern auch allgemeiner jegliche Biobeläge, Biosoils, biologisch-bedingten Beläge oder dergleichen inkl., aber nicht ausschließlich, Abbau- und Abscheidungsprodukten von Mikroorganismen, die an einer Oberfläche anhaften, z.B. an Textilien, Geschirr oder einer harten Oberfläche oder einer anderen Art von Oberfläche. Diese anhaftenden Zellen sind häufig in eine selbstproduzierte Matrix aus extrazellulärer polymerer Substanz (EPS) eingebettet. Biofilm-EPS ist ein polymeres Konglomerat, das im Allgemeinen aus extrazellulärer DNA, Proteinen und Polysacchariden besteht. Biofilme können sich auf lebenden oder nicht lebenden Oberflächen bilden. Die mikrobiellen Zellen, die in einem Biofilm wachsen, unterscheiden sich physiologisch von den planktonischen Zellen desselben Organismus, bei denen es sich im Gegensatz dazu um Einzelzellen handelt, die in einem flüssigen Medium schwimmen oder schwimmen können. Bakterienzellen, die in einem Biofilm leben, haben in der Regel deutlich andere Eigenschaften als planktonische Bakterienzellen derselben Art, da die dichte und geschützte Umgebung des Films es ihnen ermöglicht, auf verschiedene Weise zu kooperieren und zu interagieren. Ein Vorteil dieses Milieus für die Mikroorganismen ist die erhöhte Resistenz gegenüber Waschmitteln und Antibiotika, da die dichte extrazelluläre Matrix und die äußere Zellschicht das Innere der Gemeinschaft schützen. Zu den Biofilm produzierenden Bakterien auf Textilien gehören z.B. die folgenden Arten: Acinetobacter sp., Aeromicrobium sp., Brevundimonas sp., Microbacterium sp., Micrococcus luteus, Pseudomonas sp., Staphylococcus epidermidis und Stenotrophomonas sp. Auf harten Oberflächen finden sich biofilmbildende Bakterien z.B. unter den folgenden Arten: Acinetobacter sp., Aeromicrobium sp., Brevundimonas sp., Microbacterium sp., Micrococcus luteus, Pseudomonas sp, Staphylococcus epidermidis, Staphylococcus aureus und Stenotrophomonas sp. The term "biodeposit" as used herein does not only mean biofilms in the narrow sense, such as microbial deposits, biofilms or the like, which can be formed by any microorganisms whose cells adhere to each other and/or to a surface, e.g. to textiles, tableware or a hard surface or another type of surface, but also more generally any biodeposits, biosoils, biological deposits or the like including, but not limited to, degradation and deposition products of microorganisms that adhere to a surface, e.g. to textiles, tableware or a hard surface or another type of surface. These adherent cells are often embedded in a self-produced matrix of extracellular polymeric substance (EPS). Biofilm EPS is a polymeric conglomerate that generally consists of extracellular DNA, proteins and polysaccharides. Biofilms can form on living or non-living surfaces. The microbial cells that grow in a biofilm differ physiologically from the planktonic cells of the same organism, which in contrast are single cells that float or can swim in a liquid medium. Bacterial cells living in a biofilm usually have significantly different properties than planktonic bacterial cells of the same species, because the dense and protected environment of the film allows them to cooperate and interact in different ways. One advantage of this environment for the microorganisms is increased resistance to detergents and antibiotics, because the dense extracellular matrix and outer cell layer protect the interior of the community. Biofilm-producing bacteria on textiles include, for example, the following species: Acinetobacter sp., Aeromicrobium sp., Brevundimonas sp., Microbacterium sp., Micrococcus luteus, Pseudomonas sp., Staphylococcus epidermidis and Stenotrophomonas sp. Biofilm-forming bacteria found on hard surfaces include the following species: Acinetobacter sp., Aeromicrobium sp., Brevundimonas sp., Microbacterium sp., Micrococcus luteus, Pseudomonas sp, Staphylococcus epidermidis, Staphylococcus aureus and Stenotrophomonas sp.

Es wurde zudem beschrieben, dass Dispersin z.B. Biofilm und EPS abbauen kann. EP 3892708, WO 2021/122117, WO 2021/122118, WO 2021/122120, WO 2021/122121 and WO 2022/008387 describe washing and cleaning agents containing dispersin and enzymes. It has also been described that dispersin can degrade biofilm and EPS, for example.
Angesammelte organische Verschmutzungen sind oft schwer zu entfernen, und handelsübliche Wasch- und Reinigungsmittel reduzieren den Schlechtgeruch nicht ausreichend. Stattdessen wird der Schlechtgeruch durch die Verwendung verschiedener Duftstoffe überdeckt, was von den Verbrauchern oft als Reinigungseffekt empfunden wird, obwohl die Ursachen der Schlechtgerüche nicht wirklich beseitigt werden. Dies hat zur Folge, dass sich im Laufe der Zeit immer mehr organisches Material und damit immer mehr Schlechtgeruch ansammelt und immer mehr Duftstoffe zugesetzt werden müssen, damit die Textilien nicht immer schlechter riechen. Viele Duftstoffe haben jedoch Nebenwirkungen wie z.B. allergene Eigenschaften, die sich in Form von Hautausschlägen äußern können. Außerdem sind viele dieser Stoffe als Naturchemikalien umweltschädlich, wenn sie ins Abwasser gelangen. In den letzten Jahren werden Duftstoffe zunehmend in Form von Duftstoffmikrokapseln verwendet, obwohl bekannt ist, dass Mikrokapseln als Mikroplastik gelten und daher potenziell umweltschädlich sind. Außerdem sind Duftstoffe teuer und tragen zu den Gesamtkosten der Wasch- und Reinigungsmittel bei. Accumulated organic soiling is often difficult to remove and commercial detergents and cleaning agents do not sufficiently reduce the bad smell. Instead, the bad smell is masked by the use of various fragrances, which is often perceived by consumers as a cleaning effect, although the causes of the bad smell are not actually eliminated. As a result, more and more organic material and thus more and more bad smell accumulates over time and more and more fragrances have to be added to prevent the textiles from smelling worse and worse. However, many fragrances have side effects such as allergenic properties that can manifest themselves in the form of skin rashes. In addition, many of these substances are harmful to the environment as they are natural chemicals if they enter wastewater. In recent years, fragrances have been increasingly used in the form of fragrance microcapsules, although it is known that microcapsules are considered microplastics and are therefore potentially harmful to the environment. In addition, fragrances are expensive and add to the overall cost of detergents and cleaning agents.
Es besteht daher Bedarf, die Reinigungsleistung von enzymhaltigen Wasch- und/oder Reinigungsmitteln, insbesondere von vorportionierten Textilwaschmitteln, weiter zu verbessern, insbesondere im Hinblick auf hartnäckige Anschmutzungen. Weiter besteht daher Bedarf, den Schlechtgeruch in Wasch- und/oder Geschirrspülmaschinen und/oder auf den gewaschenen Textilien bzw. gereinigten Oberflächen, insbesondere Geschirr, sowie Oberflächen, insbesondere Haushaltsoberflächen, wie z.B. Oberflächen in Wasch- oder Geschirrspülmaschinen, Pumpensümpfen, Vorrats be hä Item, Wasserreservoir, Waschtrommel, Spülkammern, Wasch- oder Spülbecken, Toilettenbecken, Spülkasten, WC-Rand, Siphons, Wasserrohren und/oder -leitungen, Wasserzu- und/oder -abläufen, zu verbessern. Weiter besteht auch Bedarf, die Hygiene in Wasch- und/oder Geschirrspülmaschinen zu verbessern, sowie mikrobiell bedingte Biobeläge zuverlässig von Oberflächen, insbesondere Haushaltsoberflächen, wie z.B. Oberflächen in Wasch- oder Geschirrspülmaschinen, Pumpensümpfen, Vorrats be hä Item, Wasserreservoir, Waschtrommel, Spülkammern, Wasch- oder Spülbecken, Toilettenbecken, Spülkasten, WC-Rand, Siphons, Wasserrohren und/oder -leitungen, Wasserzu- und/oder -abläufen, zu entfernen. Mit umfasst sind dabei auch (halb-)automatisierte Wasch- oder Reinigungssystem wie z.B. Wischrobotor oder Nassstaubsauger. There is therefore a need to further improve the cleaning performance of enzyme-containing washing and/or cleaning agents, in particular of pre-portioned textile detergents, especially with regard to stubborn stains. There is also a need to improve the bad smell in washing machines and/or dishwashers and/or on the washed textiles or cleaned surfaces, in particular dishes, as well as surfaces, in particular household surfaces, such as surfaces in washing machines or dishwashers, pump sumps, storage containers, water reservoirs, washing drums, rinsing chambers, wash or sink basins, toilet bowls, cisterns, toilet rims, siphons, water pipes and/or lines, water inlets and/or outlets. There is also a need to improve hygiene in washing machines and/or dishwashers, as well as to reliably remove microbial bio-deposits from Surfaces, especially household surfaces, such as surfaces in washing machines or dishwashers, pump sumps, storage containers, water reservoirs, washing drums, rinsing chambers, wash or sink basins, toilet bowls, cisterns, toilet rims, siphons, water pipes and/or lines, water inlets and/or outlets. This also includes (semi-)automated washing or cleaning systems such as robot mops or wet vacuum cleaners.
Überraschenderweise wurde nun festgestellt, dass das erfindungsgemäße Dispersin mikrobiell bedingten Schlechtgeruch sowie mikrobiell bedingte Ablagerungen, Biobeläge und dergleichen zuverlässig von Oberflächen, insbesondere Haushaltsoberflächen, wie z.B. Oberflächen in Waschoder Geschirrspülmaschinen, Pumpensümpfen, Vorrats be hä Item, Wasserreservoir, Waschtrommel, Spülkammern, Wasch- oder Spülbecken, Toilettenbecken, Spülkasten, WC-Rand, Siphons, Wasserrohren und/oder -leitungen, Wasserzu- und/oder -abläufen, entfernt. Surprisingly, it has now been found that the dispersin according to the invention reliably removes microbially caused bad odors as well as microbially caused deposits, bio-deposits and the like from surfaces, in particular household surfaces, such as surfaces in washing machines or dishwashers, pump sumps, storage containers, water reservoirs, washing drums, rinsing chambers, wash basins or sinks, toilet bowls, cisterns, toilet rims, siphons, water pipes and/or lines, water inlets and/or outlets.

"ß-1 ,6-N-acetylglucosamnidase-Aktivität", wie hierin verwendet, ist gleichbedeutend mit "Hexosaminidase-Aktivität" und/oder "Dispersin-Aktivität" und wird wie folgt bestimmt: Zur Bestimmung der Dispersin-Aktivität werden einer Mikrotiterplatte, die pro Vertiefung 5 pl Probenlösung enthält, 35 pl Dispersin-Assay-Lösung (45 mM Citratpuffer pH 5 mit 0,5 mg/ml p-Nitrophenyl-N-acetyl- ß-D-glucosaminid) hinzugefügt. Die Mikrotiterplatte für 3 Stunden bei Raumtemperatur inkubiert. Nach Inkubation werden 40 pl Stopplösung (0,4 M Na2CO3) hinzugegeben und die Absorption bei 405 nm gemessen. Die erhaltenen Aktivitätswerte werden durch Subtraktion der für eine Referenz ohne Dispersin erhaltenen Absorptionsmessung korrigiert, um Hintergrundrauschen zu eliminieren. Daraus kann die Restaktivität (RA) für die jeweilige Dispersinvariante im Vergleich zu einem Referenzdispersin berechnet werden. "ß-1,6-N-acetylglucosamnidase activity" as used herein is synonymous with "hexosaminidase activity" and/or "dispersin activity" and is determined as follows: To determine dispersin activity, 35 μl of dispersin assay solution (45 mM citrate buffer pH 5 with 0.5 mg/ml p-nitrophenyl-N-acetyl-ß-D-glucosaminide) is added to a microtiter plate containing 5 μl of sample solution per well. The microtiter plate is incubated for 3 hours at room temperature. After incubation, 40 μl of stop solution (0.4 M Na2CO3) is added and the absorbance is measured at 405 nm. The activity values obtained are corrected by subtracting the absorbance measurement obtained for a reference without dispersin in order to eliminate background noise. From this, the residual activity (RA) for the respective dispersin variant can be calculated in comparison to a reference dispersin.
Bei den hierin genannten Enzymen handelt es sich vorzugsweise um reife (mature) Enzyme, d.h. um das katalytisch aktive Molekül ohne Signal- und/oder Propeptid(e). Soweit nicht anders angegeben beziehen sich auch die angegebenen Sequenzen auf jeweils reife (prozessierte) Enzyme. The enzymes mentioned here are preferably mature enzymes, i.e. the catalytically active molecule without signal and/or propeptide(s). Unless otherwise stated, the sequences given also refer to mature (processed) enzymes.
In verschiedenen Ausführungsformen der Erfindung ist das jeweilige Enzym ein frei vorliegendes Enzym. Dies bedeutet, dass das Enzym mit allen Komponenten des Mittels direkt agieren kann und, falls es sich bei dem Mittel um ein Flüssigmittel handelt, dass das Enzym direkt mit dem Lösungsmittel des Mittels (z.B. Wasser) in Kontakt steht. In anderen Ausführungsformen kann ein Mittel Enzyme enthalten, die einen Interaktionskomplex mit anderen Molekülen bilden oder die eine "Umhüllung" enthalten. Hierbei kann ein einzelnes oder mehrere Enzymmolekül(e) durch eine sie umgebende Struktur von den anderen Bestandteilen des Mittels getrennt sein. Eine solche trennende Struktur kann entstehen durch, ist allerdings nicht beschränkt auf, Vesikel, wie etwa eine Micelle oder ein Liposom. Die umgebende Struktur kann aber auch ein Viruspartikel, eine bakterielle Zelle oder eine eukaryotische Zelle sein. In verschiedenen Ausführungsformen kann ein Mittel Zellen von Bacillus pumilus oder Bacillus subtilus, die die erfindungsgemäßen Proteasen exprimieren, oder Zellkulturüberstände solcher Zellen enthalten. In various embodiments of the invention, the respective enzyme is a free enzyme. This means that the enzyme can interact directly with all components of the agent and, if the agent is a liquid agent, that the enzyme is in direct contact with the agent's solvent (e.g. water). In other embodiments, an agent can contain enzymes that form an interaction complex with other molecules or that contain a "coating". In this case, a single or multiple enzyme molecule(s) can be separated from the other components of the agent by a structure surrounding them. Such a separating structure can be created by, but is not limited to, vesicles, such as a micelle or a liposome. The surrounding structure can also be a virus particle, a bacterial cell or a eukaryotic cell. In various embodiments, an agent can contain cells of Bacillus pumilus or Bacillus subtilus that express the proteases according to the invention, or cell culture supernatants of such cells.
Im Zusammenhang mit der vorliegenden Erfindung bedeutet das Merkmal, dass ein Enzym die angegebene(n) Substitution(en) (oder Deletion oder Insertion) aufweist, dass sie an der jeweiligen Position eine (der angegebenen) Substitution(en) (oder Deletion oder Insertion) enthält, d.h. zumindest die angegebenen Positionen nicht anderweitig mutiert oder, beispielsweise durch Fragmentierung des Enzyms, deletiert sind. In verschiedenen Ausführungsformen weisen die hierin beschriebenen Enzyme mit Ausnahme der explizit erwähnten Substitutionen die Sequenz der jeweiligen Referenzsequenz auf, d.h. sind abgesehen von den substituierten Positionen 100% identisch zu der jeweiligen Referenzsequenz. In the context of the present invention, the feature that an enzyme has the specified substitution(s) (or deletion or insertion) means that it contains one (of the specified) substitution(s) (or deletion or insertion) at the respective position, i.e. at least the specified positions are not otherwise mutated or deleted, for example by fragmentation of the enzyme. In various embodiments, the enzymes described herein have the sequence of the respective reference sequence with the exception of the explicitly mentioned substitutions, i.e. are 100% identical to the respective reference sequence apart from the substituted positions.
Die Bestimmung der Identität von Nukleinsäure- oder Aminosäuresequenzen erfolgt durch einen Sequenzvergleich. Dieser Sequenzvergleich basiert auf dem im Stand der Technik etablierten und üblicherweise genutzten BLAST-Algorithmus (vgl. z.B. Altschul et al., Basic local alignment search tool, J. Mol. Biol., 1990, 215: 403-410, und Altschul et al., Gapped BLAST and PSI-BLAST: a new generation of protein database search programs, Nucleic Acids Res., 1997, 25: 3389-3402) und geschieht prinzipiell dadurch, dass ähnliche Abfolgen von Nukleotiden oder Aminosäuren in den Nukleinsäure- oder Aminosäuresequenzen einander zugeordnet werden. Eine tabellarische Zuordnung der betreffenden Positionen wird als Alignment bezeichnet. Ein weiterer im Stand der Technik verfügbarer Algorithmus ist der FASTA-Algorithmus. Sequenzvergleiche (Alignments), insbesondere multiple Sequenzvergleiche, werden mit Computerprogrammen erstellt. Häufig genutzt werden beispielsweise die Clustal-Serie (vgl. z.B. Chenna et al., Multiple sequence alignment with the Clustal series of programs, Nucleic Acid Res., 2003, 31 : 3497-3500), T-Coffee (vgl. z.B. Notredame et al., T-Coffee: A novel method for multiple sequence alignments, J. Mol. Biol., 2000, 302: 205-217) oder Programme, die auf diesen Programmen bzw. Algorithmen basieren. Ferner möglich sind Sequenzvergleiche (Alignments) mit dem Computer-Programm Vector NTI® Suite 10.3 (Invitrogen Corporation, 1600 Faraday Avenue, Carlsbad, Kalifornien, USA) mit den vorgegebenen Standardparametern, dessen AlignX-Modul für die Sequenzvergleiche auf ClustalW basiert, oder Clone Manager 10 (Verwendung der Scoring Matrix BLOSUM 62 für Sequenz-Alignment auf Aminosäureebene). Soweit nicht anders angegeben, wird die hierin angegebene Sequenzidentität mit dem BLAST-Algorithmus bestimmt. The identity of nucleic acid or amino acid sequences is determined by sequence comparison. This sequence comparison is based on the state-of-the-art and commonly used BLAST algorithm (see e.g. Altschul et al., Basic local alignment search tool, J. Mol. Biol., 1990, 215: 403-410, and Altschul et al., Gapped BLAST and PSI-BLAST: a new generation of protein database search programs, Nucleic Acids Res., 1997, 25: 3389-3402) and is carried out in principle by assigning similar sequences of nucleotides or amino acids in the nucleic acid or amino acid sequences to one another. A tabular assignment of the relevant positions is referred to as an alignment. Another algorithm available in the state of the art is the FASTA algorithm. Sequence comparisons (alignments), in particular multiple sequence comparisons, are created using computer programs. Commonly used programs include the Clustal series (see e.g. Chenna et al., Multiple sequence alignment with the Clustal series of programs, Nucleic Acid Res., 2003, 31 : 3497-3500), T-Coffee (see e.g. Notredame et al., T-Coffee: A novel method for multiple sequence alignments, J. Mol. Biol., 2000, 302: 205-217) or programs based on these programs or algorithms. Sequence comparisons (alignments) can also be carried out using the computer program Vector NTI® Suite 10.3 (Invitrogen Corporation, 1600 Faraday Avenue, Carlsbad, California, USA) with the specified standard parameters, whose AlignX module for sequence comparisons is based on ClustalW, or Clone Manager 10 (use of the BLOSUM 62 scoring matrix for sequence alignment at the amino acid level). Unless otherwise stated, sequence identity reported herein is determined using the BLAST algorithm.
Solch ein Vergleich erlaubt auch eine Aussage über die Ähnlichkeit der verglichenen Sequenzen zueinander. Sie wird üblicherweise in Prozent Identität, das heißt dem Anteil der identischen Nukleotide oder Aminosäurereste an denselben oder in einem Alignment einander entsprechenden Positionen angegeben. Der weiter gefasste Begriff der Homologie bezieht bei Aminosäuresequenzen konservierte Aminosäure-Austausche in die Betrachtung mit ein, also Aminosäuren mit ähnlicher chemischer Aktivität, da diese innerhalb des Proteins meist ähnliche chemische Aktivitäten ausüben. Daher kann die Ähnlichkeit der verglichenen Sequenzen auch Prozent Homologie oder Prozent Ähnlichkeit angegeben sein. Identitäts- und/oder Homologieangaben können über ganze Polypeptide oder Gene oder nur über einzelne Bereiche getroffen werden. Homologe oder identische Bereiche von verschiedenen Nukleinsäure- oder Aminosäuresequenzen sind daher durch Übereinstimmungen in den Sequenzen definiert. Solche Bereiche weisen oftmals identische Funktionen auf. Sie können klein sein und nur wenige Nukleotide oder Aminosäuren umfassen. Oftmals üben solche kleinen Bereiche für die Gesamtaktivität des Proteins essenzielle Funktionen aus. Es kann daher sinnvoll sein, Sequenzübereinstimmungen nur auf einzelne, ggf. kleine Bereiche zu beziehen. Soweit nicht anders angegeben beziehen sich Identitäts- oder Homologieangaben in der vorliegenden Anmeldung aber auf die Gesamtlänge der jeweils angegebenen Nukleinsäure- oder Aminosäuresäuresequenz. Such a comparison also allows a statement to be made about the similarity of the sequences being compared to one another. This is usually expressed in percent identity, i.e. the proportion of identical nucleotides or amino acid residues at the same positions or positions that correspond to one another in an alignment. The broader term homology includes conserved amino acid exchanges in amino acid sequences, i.e. amino acids with similar chemical activity, since these usually perform similar chemical activities within the protein. Therefore, the similarity of the sequences being compared can also be expressed as percent homology or percent similarity. Identity and/or homology statements can be made for entire polypeptides or genes or just for individual regions. Homologous or identical regions of different nucleic acid or amino acid sequences are therefore defined by similarities in the sequences. Such regions often have identical functions. They can be small and contain only a few nucleotides or amino acids. Such small regions often perform essential functions for the overall activity of the protein. It may therefore be useful to relate sequence matches only to individual, possibly small regions. Unless otherwise stated, identity or homology statements in the present application refer to the total length of the respective nucleic acid or amino acid sequence specified.
Im Zusammenhang mit der vorliegenden Erfindung bedeutet die Angabe, dass eine Aminosäureposition einer numerisch bezeichneten Position in SEQ ID NO:1 entspricht daher, dass die entsprechende Position der numerisch bezeichneten Position in SEQ ID NO:1 in einem wie oben definierten Alignment zugeordnet ist. In the context of the present invention, the statement that an amino acid position corresponds to a numerically designated position in SEQ ID NO:1 therefore means that the corresponding position is assigned to the numerically designated position in SEQ ID NO:1 in an alignment as defined above.
Für die Beschreibung von Substitutionen, die genau eine Aminosäureposition betreffen (Aminosäureaustausche), wird hierin folgende Konvention angewendet: zunächst wird die natürlicherweise vorhandene Aminosäure in Form des international gebräuchlichen Einbuchstaben- Codes bezeichnet, dann folgt die zugehörige Sequenzposition und schließlich die eingefügte Aminosäure. Mehrere oder alternative Austausche innerhalb derselben Polypeptidkette werden durch Schrägstriche voneinander getrennt. "130D/V" bedeutet somit, dass die Position 130 zu D oder V mutiert ist. Bei Insertionen sind nach der Sequenzposition zusätzliche Aminosäuren benannt. Bei Deletionen ist die fehlende Aminosäure durch ein Symbol, beispielsweise einen Stern oder einen Strich, ersetzt oder vor der entsprechenden Position ein A angegeben. Beispielsweise beschreibt P9T die Substitution von Prolin an Position 9 durch Threonin, P9TH die Insertion von Histidin nach der Aminosäure Threonin an Position 9 und P9* oder AP9 die Deletion von Prolin an Position 9. Diese Nomenklatur ist dem Fachmann auf dem Gebiet der Enzymtechnologie bekannt. For the description of substitutions that affect exactly one amino acid position (amino acid exchanges), the following convention is used: first, the naturally occurring amino acid is designated in the form of the internationally used one-letter code, then follows the corresponding sequence position and finally the inserted amino acid. Multiple or alternative exchanges within the same polypeptide chain are separated from one another by slashes. "130D/V" thus means that position 130 is mutated to D or V. In the case of insertions, additional amino acids are named after the sequence position. In the case of deletions, the missing amino acid is replaced by a symbol, for example an asterisk or a dash, or an A is indicated in front of the corresponding position. For example, P9T describes the substitution of proline at position 9 by threonine, P9TH the insertion of histidine after the amino acid threonine at position 9 and P9* or AP9 the deletion of proline at position 9. This nomenclature is known to the person skilled in the art of enzyme technology.
Einem Fachmann ist es über heutzutage allgemein bekannte Methoden, wie beispielsweise die chemische Synthese oder die Polymerase-Kettenreaktion (PCR) in Verbindung mit molekularbiologischen und/oder proteinchemischen Standardmethoden möglich, anhand bekannter DNA- und/oder Aminosäuresequenzen die entsprechenden Nukleinsäuren bis hin zu vollständigen Genen herzustellen. Derartige Methoden sind beispielsweise aus Sambrook, J., Fritsch, E.F. and Maniatis, T. 2001. Molecular cloning: a laboratory manual, 3. Edition Cold Spring Laboratory Press, bekannt. A person skilled in the art can use methods that are generally known today, such as chemical synthesis or the polymerase chain reaction (PCR) in conjunction with standard molecular biological and/or protein chemical methods, to produce the corresponding nucleic acids, including complete genes, based on known DNA and/or amino acid sequences. Such methods are known, for example, from Sambrook, J., Fritsch, E.F. and Maniatis, T. 2001. Molecular cloning: a laboratory manual, 3rd Edition Cold Spring Laboratory Press.

The cleaning performance of the enzyme thus contributes to the cleaning performance of the agent or the washing/cleaning liquor formed by the agent. The cleaning performance is preferably determined as specified below.
Unter wasch- bzw. Reinigungsflotte wird diejenige das Wasch- bzw. Reinigungsmittel enthaltende Gebrauchslösung verstanden, die auf die Textilien oder Gewebe bzw. Oberflächen, insbesondere Geschirr oder Haushaltsoberflächen, einwirkt und damit mit den auf den Textilien oder Geweben bzw. Oberflächen vorhandenen Anschmutzungen in Kontakt kommt. Üblicherweise entsteht die Wasch-ZReinigungsflotte, wenn der Wasch-ZReinigungsvorgang beginnt und das Mittel z.B. in einer Wasch- oder Geschirrspülmaschine oder in einem anderen geeigneten Behältnis mit Wasser verdünnt wird. Die Reinigungsleistung an Textilien oder Geweben kann in einem Waschsystem bestimmt werden, das ein Waschmittel in einer Dosierung zwischen 2,0 und 8,0 Gramm pro Liter Waschflotte sowie das zu untersuchende Enzym enthält. Zu vergleichende Enzyme werden konzentrationsgleich (bezogen auf aktives Protein) eingesetzt. Durch den aktivitätsgleichen Einsatz der Enzyme wird sichergestellt, dass auch bei einem etwaigen Auseinanderklaffen des Verhältnisses von Aktivsubstanz zu Gesamtprotein (die Werte der spezifischen Aktivität) die jeweiligen enzymatischen Eigenschaften, also z.B. die Reinigungsleistung an bestimmten Anschmutzungen, verglichen werden. Generell gilt, dass eine niedrige spezifische Aktivität durch Zugabe einer größeren Proteinmenge ausgeglichen werden kann. Ferner können die zu untersuchenden Enzyme auch in gleicher Stoffmenge oder Gewichtsmenge eingesetzt werden, falls die zu untersuchenden Enzyme in einem Aktivitätstest eine unterschiedliche Affinität an das Testsubstrat aufweisen. Der Ausdruck "gleiche Stoffmenge" bezieht sich in diesem Zusammenhang auf eine molgleiche Verwendung der zu untersuchenden Enzyme. Der Ausdruck "gleiche Gewichtsmenge" bezieht sich auf einen gewichtsgleichen Einsatz der zu untersuchenden Enzyme. The term washing or cleaning liquor refers to the solution containing the washing or cleaning agent that acts on the textiles or fabrics or surfaces, particularly dishes or household surfaces, and thus comes into contact with the dirt present on the textiles or fabrics or surfaces. The washing/cleaning liquor is usually created when the washing/cleaning process begins and the agent is diluted with water, for example in a washing machine or dishwasher or in another suitable container. The cleaning performance of textiles or fabrics can be determined in a washing system that contains a detergent in a dosage of between 2.0 and 8.0 grams per liter of washing liquor and the enzyme to be tested. Enzymes to be compared are used in the same concentration (based on active protein). Using the enzymes with the same activity ensures that even if there is a discrepancy in the ratio of active substance to total protein (the values of the specific activity), the respective enzymatic properties, e.g. the cleaning performance on certain stains, are compared. In general, a low specific activity can be compensated by adding a larger amount of protein. Furthermore, the enzymes to be tested can also be used in the same amount of substance or weight if the enzymes to be tested have a different affinity for the test substrate in an activity test. The term "same amount of substance" in this context refers to using the same mole of the enzymes to be tested. The term "equal amount by weight" refers to the use of equal weight of the enzymes to be investigated.
Die Konzentration des Enzyms in dem für dieses Waschsystem bestimmten Waschmittel beträgt 0,0001 bis 0,1 Gew.-%, insbesondere 0,001 bis 0,1 Gew.-%, weiter bevorzugt 0,01 bis 0,06 Gew.-% und besonders bevorzugt 0,001 bis 0,02 Gew.-%, bezogen auf aktives Protein. The concentration of the enzyme in the detergent intended for this washing system is 0.0001 to 0.1 wt.%, in particular 0.001 to 0.1 wt.%, more preferably 0.01 to 0.06 wt.% and particularly preferably 0.001 to 0.02 wt.%, based on active protein.
Die Proteinkonzentration kann mit Hilfe bekannter Methoden, zum Beispiel dem BCA-Verfahren (Bicinchoninsäure; 2,2‘-Bichinolyl-4,4‘-dicarbonsäure) oder dem Biuret-Verfahren (Gornall et al., J. Biol. Chem. 1948, 177: 751-766) bestimmt werden. Die Bestimmung der Aktivproteinkonzentration kann diesbezüglich über eine Titration der aktiven Zentren unter Verwendung eines geeigneten irreversiblen Inhibitors und Bestimmung der Restaktivität (vgl. Bender et al., J. Am. Chem. Soc. 1966, 88, 24: 5890-5913) erfolgen. The protein concentration can be determined using known methods, for example the BCA method (bicinchoninic acid; 2,2'-biquinolyl-4,4'-dicarboxylic acid) or the biuret method (Gornall et al., J. Biol. Chem. 1948, 177: 751-766). The active protein concentration can be determined by titrating the active centers using a suitable irreversible inhibitor and determining the residual activity (cf. Bender et al., J. Am. Chem. Soc. 1966, 88, 24: 5890-5913).
Ein flüssiges Referenzwaschmittel für ein solches Waschsystem kann z.B. wie folgt zusammengesetzt sein (alle Angaben in Gewichts-Prozent (Gew .-%)): 4,4% Alkylbenzolsulfonsäure, 5,6% weitere anionische Tenside, 2,4% C12-18 Na-Salze von Fettsäuren (Seifen), 4,4% nicht-ionische Tenside, 0,2% Phosphonate, 1 ,4% Zitronensäure, 0,95% NaOH, 0,01% Entschäumer, 2% Glycerin, 0,08% Konservierungsstoffe, 1% Ethanol, Rest demineralisiertes Wasser. Bevorzugt beträgt die Dosierung des flüssigen Waschmittels zwischen 3,0 und 6,0 Gramm pro Liter Waschflotte, beispielsweise 3,0, 3,2, 3,5, 3,7, 4,0, 4,5, 4,7, 4,9 oder 5,9 Gramm pro Liter Waschflotte. Bevorzugt wird gewaschen in einem pH-Wertebereich zwischen pH 7 und pH 10,5, bevorzugt zwischen pH 8 und pH 9. A liquid reference detergent for such a washing system can, for example, be composed as follows (all information in percent by weight (wt. %)): 4.4% alkylbenzenesulfonic acid, 5.6% other anionic surfactants, 2.4% C12-18 Na salts of fatty acids (soaps), 4.4% non-ionic surfactants, 0.2% phosphonates, 1.4% citric acid, 0.95% NaOH, 0.01% defoamers, 2% glycerin, 0.08% preservatives, 1% ethanol, remainder demineralized water. The dosage of the liquid detergent is preferably between 3.0 and 6.0 grams per liter of washing liquor, for example 3.0, 3.2, 3.5, 3.7, 4.0, 4.5, 4.7, 4.9 or 5.9 grams per liter of washing liquor. Washing is preferably carried out in a pH value range between pH 7 and pH 10.5, preferably between pH 8 and pH 9.
Die Reinigungsleistung wird gegenüber einer Anschmutzung auf Textil durch Messung des Reinigungsgrades der gewaschenen Textilien bestimmt. Beispielsweise kann der Waschvorgang für 60 Minuten bei einer Temperatur von 40°C erfolgen und das Wasser eine Wasserhärte zwischen 15,5°dH und 16,5°dH (deutsche Härte) aufweisen. The cleaning performance is determined by measuring the degree of cleaning of the washed textiles compared to soiling on textiles. For example, the washing process can take place for 60 minutes at a temperature of 40°C and the water can have a water hardness between 15.5°dH and 16.5°dH (German hardness).
Der Weißegrad, d.h. die Aufhellung der Anschmutzungen, als Maß für die Reinigungsleistung wird mit optischen Messverfahren bestimmt, bevorzugt photo metrisch. Ein hierfür geeignetes Gerät ist beispielsweise das Spektrometer Minolta CM508d. Üblicherweise werden die für die Messung eingesetzten Geräte zuvor mit einem Weißstandard, bevorzugt einem mitgelieferten Weißstandard, kalibriert. The degree of whiteness, ie the lightening of the soiling, as a measure of the cleaning performance is determined using optical measuring methods, preferably photometric. A suitable device for this is for example the Minolta CM508d spectrometer. The devices used for the measurement are usually calibrated beforehand with a white standard, preferably a supplied white standard.
Die Reinigungsleistung an Oberflächen, insbesondere Haushaltsoberflächen, bevorzugt in Wasch- oder Geschirrspülmaschinen, Pumpensümpfen, Vorrats be hä Item, Wasserreservoir, Waschtrommel, Spülkammern, Wasch- oder Spülbecken, Toilettenbecken, Spülkasten, WC-Rand, Siphons, Wasserrohren und/oder -leitungen, Wasserzu- und/oder -abläufen, kann wie in Beispiel 1 beschrieben bestimmt werden. The cleaning performance on surfaces, in particular household surfaces, preferably in washing machines or dishwashers, pump sumps, storage containers, water reservoirs, washing drums, rinsing chambers, wash basins or sinks, toilet bowls, cisterns, WC rims, siphons, water pipes and/or lines, water inlets and/or outlets, can be determined as described in Example 1.

Ferner können die in dem Mittel enthaltenen Enzyme und/oder weitere Inhaltsstoffe des Mittels mit einer bei Raumtemperatur oder bei Abwesenheit von Wasser für das Enzym undurchlässigen Substanz umhüllt sein, welche unter Anwendungsbedingungen des Mittels durchlässig für das Enzym wird. Eine solche Ausführungsform der Erfindung ist somit dadurch gekennzeichnet, dass das Enzyme mit einer bei Raumtemperatur oder bei Abwesenheit von Wasser für das Enzym undurchlässigen Substanz umhüllt ist. Weiterhin kann auch das Mittel selbst in einem Behältnis, vorzugsweise einem luftdurchlässigen Behältnis, verpackt sein, aus dem es kurz vor Gebrauch oder während des Waschvorgangs freigesetzt wird. Furthermore, the enzymes contained in the agent and/or other ingredients of the agent can be coated with a substance that is impermeable to the enzyme at room temperature or in the absence of water, which substance becomes permeable to the enzyme under the conditions of use of the agent. Such an embodiment of the invention is thus characterized in that the enzyme is coated with a substance that is impermeable to the enzyme at room temperature or in the absence of water. Furthermore, the agent itself can also be packaged in a container, preferably an air-permeable container, from which it is released shortly before use or during the washing process.

Organic cobuilders include, in particular, polycarboxylates/polycarboxylic acids, polymeric polycarboxylates, aspartic acid, polyacetals, dextrins, other organic cobuilders and phosphonates. These classes of substances are described below. Organic cobuilder substances can, if desired, be present in amounts of up to 40% by weight, in particular up to 25% by weight and preferably from 1 to 8% by weight. Useful organic builder substances are, for example, polycarboxylic acids which can be used in the form of the free acid and/or their sodium salts, whereby polycarboxylic acids are understood to be carboxylic acids which have more than one acid function.

In addition to their builder effect, the free acids typically also have the property of an acidifying component and thus also serve to adjust a lower and milder pH value of agents. Citric acid, succinic acid, glutaric acid, adipic acid, gluconic acid and any mixtures of these are particularly suitable. Citric acid or salts of citric acid are particularly preferably used as the builder substance. Other particularly preferred builder substances are selected from methylglycine disidic acid (MGDA), glutamic acid diacetate (GLDA), aspartic acid diacetate (ASDA), hydroxyethyliminodiacetate (HEIDA), iminodisuccinate (IDS) and ethylenediamine disuccinate (EDDS), carboxymethylinulin and polyaspartate.

Bei den für polymere Polycarboxylate angegebenen Molmassen handelt es sich im Sinne dieser Anmeldung um gewichtsmittlere Molmassen Mw der jeweiligen Säureform, die grundsätzlich mittels Gelpermeationschromatographie (GPC) bestimmt wurden, wobei ein UV-Detektor eingesetzt wurde. Die Messung erfolgte dabei gegen einen externen Polyacrylsäure-Standard, der aufgrund seiner strukturellen Verwandtschaft mit den untersuchten Polymeren realistische Molgewichtswerte liefert. Diese Angaben weichen deutlich von den Molgewichtsangaben ab, bei denen Polystyrolsulfonsäuren als Standard eingesetzt werden. Die gegen Polystyrolsulfonsäuren gemessenen Molmassen sind in der Regel deutlich höher als die in dieser Anmeldung angegebenen Molmassen. Geeignete Polymere sind insbesondere Polyacrylate, die bevorzugt eine Molekülmasse von 2000 bis 20000 g/mol aufweisen. Aufgrund ihrer überlegenen Löslichkeit können aus dieser Gruppe wiederum die kurzkettigen Polyacrylate, die Molmassen von 2000 bis 10000 g/mol, und besonders bevorzugt von 3000 bis 5000 g/mol, aufweisen, bevorzugt sein. Geeignet sind weiterhin Copolymere Polycarboxylate, insbesondere solche der Acrylsäure mit Methacrylsäure und der Acrylsäure oder Methacrylsäure mit Maleinsäure. Als besonders geeignet haben sich Copolymere der Acrylsäure mit Maleinsäure erwiesen, die 50 bis 90 Gew.-% Acrylsäure und 50 bis 10 Gew.-% Maleinsäure enthalten. Ihre relative Molekülmasse, bezogen auf freie Säuren, beträgt im Allgemeinen 2000 bis 70000 g/mol, vorzugsweise 20000 bis 50000 g/mol und insbesondere 30000 bis 40000 g/mol. Polymeric polycarboxylates are also suitable as builders. These include, for example, the alkali metal salts of polyacrylic acid or polymethacrylic acid, e.g. those with a relative molecular mass of 500 to 70,000 g/mol. For the purposes of this application, the molar masses given for polymeric polycarboxylates are weight-average molar masses Mw of the respective acid form, which were generally determined by means of gel permeation chromatography (GPC) using a UV detector. The measurement was carried out against an external polyacrylic acid standard, which provides realistic molar weight values due to its structural similarity to the polymers examined. These details differ significantly from the molar weight details for which polystyrene sulfonic acids are used as a standard. The molar masses measured against polystyrene sulfonic acids are generally significantly higher than the molar masses given in this application. Suitable polymers are in particular polyacrylates, which preferably have a molecular weight of 2000 to 20,000 g/mol. Due to their superior solubility, the short-chain polyacrylates from this group, which have molecular weights of 2000 to 10,000 g/mol, and particularly preferably of 3000 to 5000 g/mol, may be preferred. Also suitable are copolymers of polycarboxylates, in particular those of acrylic acid with methacrylic acid and of acrylic acid or methacrylic acid with maleic acid. Copolymers of acrylic acid with maleic acid, which contain 50 to 90% by weight of acrylic acid and 50 to 10% by weight of maleic acid, have proven to be particularly suitable. Their relative molecular weight, based on free acids, is generally 2000 to 70,000 g/mol, preferably 20,000 to 50,000 g/mol and in particular 30,000 to 40,000 g/mol.

In Mitteln, die sowohl amorphe als auch kristalline Alkalisilikate enthalten, beträgt das Gewichtsverhältnis von amorphem Alkalisilikat zu kristallinem Alkalisilikat vorzugsweise 1 :2 bis 2:1 und insbesondere 1 :1 bis 2:1 . Kristalline schichtförmige Silikate der oben angegebenen Formel (I) werden von der Fa. Clariant GmbH unter dem Handelsnamen Na-SKS vertrieben, z.B.

In den hierin beschriebenen Reinigungsmitteln können die einzusetzenden Enzyme ferner zusammen mit Begleitstoffen, etwa aus der Fermentation, konfektioniert sein. In flüssigen Formulierungen werden die Enzyme bevorzugt als Enzymflüssigformulierung(en) eingesetzt. In the cleaning agents described here, the enzymes to be used can also be formulated together with accompanying substances, for example from fermentation. In liquid formulations, the enzymes are preferably used as enzyme liquid formulation(s).
Die Enzyme werden in der Regel nicht in Form des reinen Proteins, sondern vielmehr in Form stabilisierter, lager- und transportfähiger Zubereitungen bereitgestellt. Zu diesen vorkonfektionierten Zubereitungen zählen beispielsweise die durch Granulation, Extrusion oder Lyophilisierung erhaltenen festen Präparationen oder, insbesondere bei flüssigen oder gelförmigen Mitteln, Lösungen der Enzyme, vorteilhafterweise möglichst konzentriert, wasserarm und/oder mit Stabilisatoren oder weiteren Hilfsmitteln versetzt. The enzymes are generally not provided in the form of pure protein, but rather in the form of stabilized, storable and transportable preparations. These prefabricated preparations include, for example, solid preparations obtained by granulation, extrusion or lyophilization or, in particular in the case of liquid or gel-like products, solutions of the Enzymes, preferably as concentrated as possible, low in water and/or mixed with stabilizers or other additives.
Alternativ können die Enzyme sowohl für die feste als auch für die flüssige Darreichungsform verkapselt werden, beispielsweise durch Sprühtrocknung oder Extrusion der Enzymlösung zusammen mit einem vorzugsweise natürlichen Polymer oder in Form von Kapseln, beispielsweise solchen, bei denen die Enzyme wie in einem erstarrten Gel eingeschlossen sind oder in solchen vom Kern-Schale- Typ, bei dem ein enzymhaltiger Kern mit einer Wasser-, Luft- und/oder Chemikalien-undurchlässigen Schutzschicht überzogen ist. In aufgelagerten Schichten können zusätzlich weitere Wirkstoffe, beispielsweise Stabilisatoren, Emulgatoren, Pigmente, Bleich- oder Farbstoffe aufgebracht werden. Derartige Kapseln werden nach an sich bekannten Methoden, beispielsweise durch Schüttel- oder Rollgranulation oder in Fluid-bed-Prozessen aufgebracht. Vorteilhafterweise sind derartige Granulate, beispielsweise durch Aufbringen polymerer Filmbildner, staubarm und aufgrund der Beschichtung lagerstabil. Alternatively, the enzymes can be encapsulated for both the solid and liquid dosage forms, for example by spray drying or extrusion of the enzyme solution together with a preferably natural polymer or in the form of capsules, for example those in which the enzymes are enclosed as if in a solidified gel or in those of the core-shell type, in which an enzyme-containing core is coated with a protective layer that is impermeable to water, air and/or chemicals. In addition, other active ingredients, such as stabilizers, emulsifiers, pigments, bleaching agents or dyes, can be applied in superimposed layers. Such capsules are applied using methods known per se, for example by shaking or rolling granulation or in fluid bed processes. Such granules are advantageously low in dust, for example by applying polymeric film formers, and are stable in storage due to the coating.
Weiterhin ist es möglich, zwei oder mehrere Enzyme zusammen zu konfektionieren, so dass ein einzelnes Granulat mehrere Enzymaktivitäten aufweist. Furthermore, it is possible to package two or more enzymes together so that a single granulate has several enzyme activities.
Die Enzyme können auch in wasserlösliche Filme, wie sie beispielsweise bei der Konfektionierung von Wasch- und Reinigungsmitteln in Einheitsdosisform verwendet werden, eingebracht werden. Ein derartiger Film ermöglicht die Freisetzung der Enzyme nach Kontakt mit Wasser. Wie hierin verwendet, bezieht sich "wasserlöslich" auf eine Filmstruktur, die vorzugsweise vollständig wasserlöslich ist. Bevorzugt besteht ein solcher Film aus (vollständig oder teilweise hydrolysiertem) Polyvinylalkohol (PVA). The enzymes can also be incorporated into water-soluble films, such as those used in the packaging of detergents and cleaning agents in unit dosage form. Such a film enables the release of the enzymes after contact with water. As used herein, "water-soluble" refers to a film structure that is preferably completely water-soluble. Preferably, such a film consists of (fully or partially hydrolyzed) polyvinyl alcohol (PVA).
Die erfindungsgemäßen Mittel können einen oder mehrere reversible Enzyminhibitor(en)/- stabilisator(en) umfassen. Die erfindungsgemäßen Mittel können den/die reversiblen Enzyminhibitor(en)/-stabilisator(en) in einer Konzentration von 0,1 bis 2 Gew.-%, vorzugsweise 0,3 bis 1 ,5 Gew.-%, enthalten, bezogen auf das Gesamtgewicht des Mittels.

"Essentially free of boron-containing compounds" in this context means that the agents according to the invention contain less than 2% by weight, preferably less than 1% by weight, more preferably less than 0.5% by weight and particularly preferably less than 0.1% by weight, of boron-containing compounds, based on the total weight of the agent. In very particularly preferred embodiments, the agents according to the invention are free of boron-containing compounds, i.e. they contain in particular no boric acid and/or phenylboronic acid derivatives.
In verschiedenen Ausführungsformen können das Enzym und die Inhibitor/Stabilisatorverbindung in einer Enzymzusammensetzung vorformuliert vorliegen. Wie aus den vorherigen Ausführungen ersichtlich, bildet das Enzym-Protein nur einen Bruchteil des Gesamtgewichts üblicher Enzym- Zubereitungen. Bevorzugt eingesetzte Enzym-Zubereitungen enthalten zwischen 0,1 und 40 Gew.-%, bevorzugt zwischen 0,2 und 30 Gew.-%, besonders bevorzugt zwischen 0,4 und 20 Gew.-% und insbesondere zwischen 0,8 und 10 Gew.-% des Enzymproteins. In solchen Zusammensetzungen kann die Inhibitor/Stabilisatorverbindung in einer Menge von 0,05 bis 35 Gew.-%, vorzugsweise von 0,05 bis 10 Gew.-%, bezogen auf das Gesamtgewicht in der Enzymzusammensetzung, enthalten sein. Diese Enzymzusammensetzung, die ebenfalls ein Bestandteil der vorliegenden Erfindung ist, kann dann in erfindungsgemäßen Mitteln eingesetzt werden, und zwar in Mengen, die zu den oben angegeben Endkonzentrationen im Mittel führen. In various embodiments, the enzyme and the inhibitor/stabilizer compound can be pre-formulated in an enzyme composition. As can be seen from the previous statements, the enzyme protein only forms a fraction of the total weight of conventional enzyme preparations. Preferably used enzyme preparations contain between 0.1 and 40% by weight, preferably between 0.2 and 30% by weight, particularly preferably between 0.4 and 20% by weight and in particular between 0.8 and 10% by weight of the enzyme protein. In such compositions, the inhibitor/stabilizer compound can be present in an amount of 0.05 to 35% by weight, preferably from 0.05 to 10% by weight, based on the total weight in the enzyme composition. This enzyme composition, which is also a component of the present invention, can then be used in agents according to the invention, in amounts that lead to the final concentrations in the agent specified above.

Vor dem Versuchsstart wurde die verwendete Haushaltswaschmaschine (Miele Novotronic W1514) sensorisch und hinsichtlich der Belags-/ Biobelagsbildung am Pumpensumpf der Waschmaschine optisch beurteilt (- = kein Biobelag, + = leichter Biobelag, ++ = starker Biobelag). Zur Vorbereitung wurden des Weiteren ca. 2,0 kg weiße Textilien (T-Shirts, Frottierhandtücher) durch wiederholtes Waschen mit einem bleichehaltigen, handelsüblichen Vollwaschmittel im Intensivprogramm (95°C, 16°dH, 1400 U/min, Miele Novotronic W1514)) gereinigt und desinfiziert, und in einem Wäschetrockner getrocknet. Durch wiederholtes Waschen (30°C, 16°dH, 1400 U/min, 120 min) und Lagern unter standardisierten Bedingungen der vorbereiteten Wäsche in der vorbereiteten Haushaltswaschmaschine wurden typische Haushaltswaschbedingungen simuliert und dadurch entsprechende Belags-ZBiobelagsbildung in der Waschmaschine hervorgerufen. Zwischen den Waschzyklen wurde die Wäsche außerhalb der Waschmaschine gelagert und die Waschmaschine mit geschlossener Tür inkubiert. Nach dem letzten Waschzyklus wurde die Waschmaschine (d.h. die geöffnete Waschtrommel) sensorisch von einem gemischten Expert-ZVerbraucher-Panel beurteilt (Schlechtgeruch Skala 0-3, 0 = kein Schlechtgeruch, 3 = starker Schlechtgeruch; Differenz > 0,5 = signifikant). Zusätzlich zur sensorischen Beurteilung wurde auch die Belags-Z Biobelagsbildung am Pumpensumpf der Waschmaschine optisch beurteilt (- = kein Biobelag, + = leichter Biobelag, ++ = starker Biobelag). Before the start of the test, the household washing machine used (Miele Novotronic W1514) was assessed sensorially and visually with regard to the formation of deposits/biodeposits on the pump sump of the washing machine (- = no biodeposit, + = slight biodeposit, ++ = strong biodeposit). In preparation, approx. 2.0 kg of white textiles (T-shirts, terry towels) were cleaned and disinfected by repeatedly washing them with a commercially available heavy-duty detergent containing bleach in the intensive program (95°C, 16°dH, 1400 rpm, Miele Novotronic W1514)) and dried in a tumble dryer. By repeatedly washing (30°C, 16°dH, 1400 rpm, 120 min) and storing the prepared laundry under standardized conditions in the prepared household washing machine, typical household washing conditions were simulated and the corresponding formation of deposits/biodeposits was induced in the washing machine. Between the washing cycles, the laundry was stored outside the washing machine and the washing machine was incubated with the door closed. After the last washing cycle, the washing machine (ie the opened washing drum) was assessed sensorially by a mixed expert-consumer panel (bad smell scale 0-3, 0 = no bad smell, 3 = strong bad smell; difference > 0.5 = significant). In addition to the sensory assessment, the formation of deposits on the The washing machine's pump sump was visually assessed (- = no bio-deposit, + = light bio-deposit, ++ = heavy bio-deposit).
