Description

  The present invention relates to an aureobasidium culture obtained from an aureobasidium culture medium containing β-glucan. The aureobasidium culture of the present invention has a bioregulatory function and a physiologically active function, and is suitably used for foods, pharmaceuticals, cosmetics, feeds, chemical products and the like.

  β-glucan is contained in large amounts in cell walls of yeast, basidiomycetes, fungi, lactic acid bacteria, and other microorganisms. In addition, cells that secrete β-glucan outside the cells are also known. The cell walls and extracts of these microorganisms and basidiomycetes, and β-glucan secreted and produced outside the cells have physiological functions such as antitumor activity and immune enhancement, and therefore are being applied to food and cosmetics. In particular, β-glucans derived from basidiomycetes contained in the fruiting bodies and mycelium of basidiomycetes have been used as pharmaceuticals. However, the amount of β-glucan contained in basidiomycetes varies greatly depending on the growth / cultivation conditions, and it is necessary to separate β-glucan by extraction, and the resulting β-glucan is complex and has a wide variety of molecular species. The quality is unstable, such as a mixture of high and low molecular weight substances. As a strain that secretes and produces β-glucan outside the fungus body, there is a strain of the genus Aureobasidium (Aureobasidium sp.), And its culture solution (Aureobasidium culture solution) is used as a food or drink or food additive. I came. The β-glucan contained therein has a β-1,3-bonded glucose residue as a main chain, and this glucose residue has a β-1,6-bonded glucose residue as a side chain (branched chain). 1,6-β-D-glucan is well known (see Non-Patent Document 1 and Non-Patent Document 2).

However, the β-glucan content of the aureobasidium culture solution obtained by culturing the microorganism of the genus Aureobasidium is about 0.1 to 0.2% by mass, which is very inefficient. In addition, these microorganisms belonging to the genus Aureobasidium are called black yeasts by common names, and the cells or culture solution are colored black by the melanin pigment produced by the cells, and the resulting β-glucan is also colored. The β-glucan that is produced has a significantly deteriorated quality. In addition, the viscosity of the culture solution is high and coagulation is difficult to handle, and due to changes over time, further coloring occurs, water solubility changes, thickening, odor generation, etc., causing problems Yes.

It is preferable from the content of 6-β-D-glucan, the problem of change over time, the ease of obtaining a concentrate, and the like. In addition, the microorganisms separated in the environment (for example, food, soil, indoors, etc.) can be used. Moreover, the stock strain or isolate isolate | separated by single bacteria, Furthermore, the mutant strain which performed mutation operation in them by a conventional method can be used. Examples of the mutation operation include UV treatment, chemical treatment with nitrosoguanidine, ethidium bromide, ethyl methanesulfonate, sodium nitrite, and the like.

The medium for culturing these microorganisms belonging to the genus Aureobasidium may be a medium containing nutrient sources (carbon source, nitrogen source, inorganic salts) that can be normally used by microorganisms belonging to the genus Aureobasidium, and further if necessary. A normal medium containing an organic nutrient source can be used, and various synthetic media, semi-synthetic media, natural media, and the like can be used.
As the carbon source, saccharides are preferable. Examples include monosaccharides such as glucose, sucrose, fructose, mannose, galactose, xylose and arabinose, disaccharides such as maltose, lactose and trehalose, oligosaccharides such as fructooligosaccharide and xylooligosaccharide, dextrin and starch Polysaccharides can be used alone or in combination. In addition, alcohols such as glycerol and ethylene glycol, sugar alcohols such as mannitol, sorbitol, and erythritol, organic acids, and the like are appropriately used.
