The amino butanoic acid high content fermentation food and the manufacturing method which use the lactobacillus, and its lactobacillus which possess amino butanoic acid high productivity.

摘要

PROBLEM TO BE SOLVED: To obtain the subject new lactic acid bacterium comprising Lactobacillus brevis TY414 having high productivity of γ-aminobutyric acid and capable of efficiently providing the γ-aminobutyric acid having suppressing actions on blood pressure elevation and useful for a food, etc., having high health directivity in a short time. ;SOLUTION: This lactic acid bacterium is new Lactobacillus brevis TY414 (FERM P-16910) having the following mycological properties and high productivity of γ- aminobutyric acid, an incipient pH 5.7 in an MRS liquid culture medium; the form of the microorganism when cultured at 30°C for 16 hr: the form of the microorganism: bacillary; Gram staining: positive; motility: none; spore: none; catalase: none; facultative anaerobic property; growth temperature range: 20-40°C; growth pH range: 3.8-9.4; lactic acid fermentation: heterofermentative; optical rotatory power of lactic acid: DL; fermenting property of saccharide; strong fermentation L-arabinose, ribose, D- xylose, galactose, glucose, fructose, etc., weak fermentation mannitol, N- acetylglucosamine, cellobiose, etc. The resultant lactic acid bacterium is used for producing the γ-aminobutyric acid useful for a food, etc., having high health directivity.;COPYRIGHT: (C)2000,JPO
