Description
本発明は、乳酸菌を使用したD−アミノ酸の製造方法に関する。また、当該製造方法に適した新規乳酸菌に関する。当該方法により製造されるD−アミノ酸、又は新規乳酸菌の培養物は、医薬、医薬部外品、皮膚外用剤、化粧料、飲食品、食品添加物、及び飼料等の組成物に配合して利用することができる。 The present invention relates to a method for producing a D-amino acid using lactic acid bacteria. Moreover, it is related with the novel lactic acid bacteria suitable for the said manufacturing method. The culture of D-amino acid or a novel lactic acid bacterium produced by the method is used by blending it with a composition such as a pharmaceutical, a quasi-drug, an external preparation for skin, a cosmetic, a food or drink, a food additive, and a feed. can do.
アミノ酸には、D体、L体が存在するが、哺乳類の体内に存在するアミノ酸はL体がほとんどであると考えられてきた。しかし近年、測定技術の進歩により、いくつかのD―アミノ酸が人間の体内に存在することが明らかとなってきた。また、D−アミノ酸は、特徴的な生理作用を示し、当該生理作用は、L−アミノ酸とは異なること等が報告されている。 There are D-forms and L-forms of amino acids, but it has been considered that most of amino acids present in mammalian bodies are L-forms. However, in recent years, it has become clear that several D-amino acids are present in the human body due to advances in measurement technology. In addition, D-amino acids exhibit a characteristic physiological action, and it has been reported that the physiological action is different from that of L-amino acids.
D−アミノ酸に関する研究は、神経伝達やホルモン調節との関連といった生理学的、医学的な観点からのアプローチが主流であった。たとえば、D−セリンは、中枢神経系に偏在しており、NMDA受容体チャネルの分布と強い正の相関を示すことから、その作用が注目されている。NMDA受容体は、その機能が高まると、記憶、学習能力も高まることが知られている。そして、D−セリンまたはD−アラニンは、NMDA受容体活性を増強することが明らかとなっている(非特許文献1)。 Studies on D-amino acids have mainly been approaches from physiological and medical viewpoints such as the relationship with neurotransmission and hormone regulation. For example, D-serine is ubiquitous in the central nervous system and shows a strong positive correlation with the distribution of NMDA receptor channels. NMDA receptors are known to increase memory and learning ability as their functions increase. And it has become clear that D-serine or D-alanine enhances NMDA receptor activity (Non-patent Document 1).
D−アラニンは、血糖値の制御に関与すること(非特許文献2)、及び、コラーゲン産生促進作用を有すること(特許文献1)が知られている。また、D−プロリンは紫外線傷害を軽減することから、紫外線が関与するシワの抑制のみならず、医薬として白内障等への適用も期待されている(特許文献2)。 It is known that D-alanine is involved in the control of blood glucose level (Non-patent Document 2) and has a collagen production promoting action (Patent Document 1). In addition, since D-proline reduces UV damage, it is expected not only to suppress wrinkles involving UV light but also to be applied to cataract as a pharmaceutical (Patent Document 2).
D−アミノ酸はヒトの皮膚(角層)に存在し、加齢とともにD−アスパラギン酸が減少すること、及びD−アスパラギン酸がL−アスパラギン酸より優れた美肌効果を有することが明らかとなっている(非特許文献3)。上記効果から、現在は、D−アスパラギン酸を豊富に含む製品が市販されている。
D−アミノ酸が有する皮膚に対する効能としては、他にも、D−グルタミン酸が、経口投与により、シワ形成を軽減させることが知られている(特許文献3)。
It is clear that D-amino acid is present in human skin (stratum corneum), D-aspartic acid decreases with age, and D-aspartic acid has a skin beautifying effect superior to L-aspartic acid. (Non-patent Document 3). Because of the above effects, products rich in D-aspartic acid are currently on the market.
As other skin effects of D-amino acids, it is known that D-glutamic acid reduces wrinkle formation by oral administration (Patent Document 3).
D−アスパラギン酸は、松果体実質細胞に存在し、精巣ライディッヒ細胞のテストステロン産生の亢進などに関与することから、生殖機能の改善に関与する可能性が示唆されている(非特許文献4)。 D-aspartic acid is present in pineal parenchymal cells and is involved in enhancement of testosterone production in testicular Leydig cells, suggesting the possibility of being involved in the improvement of reproductive function (Non-patent Document 4). .
D−ヒスチジンは、食欲抑制による抗肥満作用を有することから、メタボリックコントロール等の体重コントロールに使用することが期待されている(非特許文献5)。 Since D-histidine has an anti-obesity action by suppressing appetite, it is expected to be used for weight control such as metabolic control (Non-patent Document 5).
また、人の体に働きかける作用の他にも、D−グルタミン酸は、防腐剤の防腐力低下を抑制することが知られている(特許文献4)。よって、化粧料及び食品、医薬等の組成物にD−グルタミン酸を配合することにより、防腐剤の量を減らすことができる。一般に、防腐剤には、皮膚刺激を起こしたり、発がん性が懸念されているものもあるため、防腐剤を減らすことは、安全性の面で有益である。さらに、D−グルタミン酸の有益な生理作用も享受することができる。 In addition to the action acting on the human body, it is known that D-glutamic acid suppresses the decrease in the preservative power of the preservative (Patent Document 4). Therefore, the amount of the preservative can be reduced by blending D-glutamic acid in the composition of cosmetics, food, medicine and the like. In general, some preservatives cause skin irritation or carcinogenicity, and therefore reducing the preservatives is beneficial in terms of safety. Furthermore, the beneficial physiological action of D-glutamic acid can also be enjoyed.
一方、近年は、D−アミノ酸に関して、食品分野からのアプローチも始まっている。遊
離のアミノ酸の味は、L体とD体とでは大きく異なることが知られているが、L体と同様にD体も風味改良剤として使用し得る(特許文献5)。そして、チーズ、ヨーグルト、黒酢又は日本酒等の発酵食品には、D−アミノ酸が豊富に含まれており、発酵食品の旨みの一役を担っていると考えられている。
On the other hand, in recent years, approaches from the food field have also begun for D-amino acids. Although it is known that the taste of free amino acids differs greatly between L-form and D-form, D-form can be used as a flavor improving agent as well as L-form (Patent Document 5). And fermented foods such as cheese, yogurt, black vinegar or sake contain abundant D-amino acids and are considered to play a role in the taste of fermented foods.
非特許文献6は、生もと造りの日本酒は、含有されるD−アミノ酸濃度が高い傾向があり、それらD−アミノ酸は日本酒の旨味や総合評価を高めること、及び、それらD−アミノ酸は生もと由来の乳酸菌(Lactobacillus sakei等)が生産していることを、明らかにしている。しかし、ラクトバチルス・ヘルベティカスがD−アミノ酸を生産していることに関する記載はない。 Non-Patent Document 6 shows that sake made from raw products tends to have a high concentration of D-amino acids, and these D-amino acids enhance the umami and overall evaluation of sake, and those D-amino acids are raw. It is clarified that lactic acid bacteria (Lactobacillus sakei etc.) derived from the origin are producing. However, there is no description about Lactobacillus helveticus producing D-amino acids.
上記のように、D−アミノ酸は、生理・生化学、食品学などに関係する研究から、さまざまな用途が期待されており、食品、医薬品、化粧料などの分野における新しい機能成分として使用されると考えられている。しかし、D−アミノ酸は光学活性を有するアミノ酸であり、光学的に純度の高いD−アミノ酸の製造は困難であることが知られている。 As described above, D-amino acids are expected to have various uses from research related to physiology / biochemistry, food science, and the like, and are used as new functional ingredients in the fields of food, pharmaceuticals, cosmetics, and the like. It is believed that. However, D-amino acids are optically active amino acids, and it is known that it is difficult to produce optically pure D-amino acids.
これまでに、乳酸菌等の微生物の細胞内には、多くのD−アミノ酸が存在することが報告されている(非特許文献7)。また、当該微生物または当該微生物が産生する酵素を用いて、D−アミノ酸を製造する方法が知られている(特許文献6、7)。しかし、微生物の体内に存在することが報告されているD体の種類は限られており、また、L体に対するD体の比率も高くないため、効率がいい方法とはいえない。さらに、D−アミノ酸は、医薬、医薬部外品、化粧料、食品、及び飼料等の材料として使用され得ることから、高純度のものが求められているところ、上記の方法では、微生物由来の不純物が少なからず混入する可能性があった。 So far, it has been reported that many D-amino acids are present in cells of microorganisms such as lactic acid bacteria (Non-patent Document 7). Moreover, the method of manufacturing D-amino acid using the said microorganism or the enzyme which the said microorganism produces is known (patent documents 6, 7). However, the types of D-forms that have been reported to exist in the body of microorganisms are limited, and the ratio of D-forms to L-forms is not high, so it cannot be said to be an efficient method. Furthermore, since D-amino acids can be used as materials for pharmaceuticals, quasi drugs, cosmetics, foods, feeds, and the like, high purity ones are required. There was a possibility that not a few impurities were mixed.
一方、ラクトバチルス・ヘルベティカスは、これまでに、動脈硬化予防(特許文献8)、アトピー性皮膚炎治療(特許文献9)、脂肪肝抑制(特許文献10)、内臓脂肪蓄積抑制(特許文献11)等の様々な用途が知られており、これらの用途に基づいて、医薬、飲食品、化粧料等の分野において使用されてきた。 On the other hand, Lactobacillus helveticus has been used to prevent arteriosclerosis (Patent Document 8), atopic dermatitis treatment (Patent Document 9), fatty liver suppression (Patent Document 10), visceral fat accumulation suppression (Patent Document 11). Are known, and based on these uses, they have been used in the fields of medicine, food and drink, cosmetics, and the like.
本発明は、乳酸菌を用いて、高効率でD−アミノ酸を製造する方法を提供することを課題とする。また、当該D−アミノ酸の製造方法に、特に適した新規乳酸菌株を提供することを課題とする。 An object of the present invention is to provide a method for producing a D-amino acid with high efficiency using lactic acid bacteria. Another object of the present invention is to provide a novel lactic acid strain particularly suitable for the production method of the D-amino acid.

ラクトバチルス・ヘルベティカスMCC1848株の菌学的性質は、バージェイズ・マニュアル・オブ・システマティック・バクテリオロジー(Bergey's Manual of Systematic Bacteriology, Volume 3、William B. Whitman, Aidan C. Partel 著、Williams and Wilkins Company、2009年)にほぼ従って測定した。その結果、MCC1848株は、グラム陽性の桿菌であり、BL寒天培地で培養した場合、グレーがかった円形扁平状で粗面なコロニーを形成することが分かった。
The bacteriological properties of Lactobacillus helveticus MCC1848 strain are described in Bergey's Manual of Systematic Bacteriology,
その他の菌学的性質として、グルコースからのガス産生、糖発酵性について、表1に示す。糖発酵性については、光岡の糖発酵性用培地(1974年、光岡知足著「乳酸菌の細
菌学」、臨床検査18、1163〜1172ページ)を用いて、28種類の糖について試験を行った。MCC1848株の糖発酵性は、国際的な細菌分類の大網である前記バージェイズ・マニュアル・オブ・システマティック・バクテリオロジーに記載されているラクトバチルス・ヘルベティカスに特徴的な糖発酵性と一致し、標準株であるJCM1120株の糖発酵性とも酷似している。これらのことから、MCC1848株は、ヘルベティカスに属すると考えられる。参考として、標準株の糖発酵性と、バージェイズ・マニュアルの記載を一部抜粋し、表1に示す。
As other mycological properties, Table 1 shows gas production from glucose and sugar fermentability. For sugar fermentability, 28 types of sugars were tested using Mitsuoka's medium for sugar fermentability (1974, Tomochitsu Mitsuoka, “Bacteriology of Lactic Acid Bacteria”, Clinical Examination 18, pages 1163-1172). The sugar fermentability of the MCC1848 strain is consistent with the sugar fermentability characteristic of Lactobacillus helveticus described in the above-mentioned Barjays Manual of Systematic Bacteriology, which is an omentum of international bacterial classification. It is very similar to the sugar fermentability of the standard strain JCM1120. From these facts, MCC1848 strain is considered to belong to Helveticas. For reference, the sugar fermentability of the standard strain and a part of the description in the Barjays Manual are excerpted and shown in Table 1.
