METHODS OF PRODUCING Ϝ-AMINOBUTYRIC ACID AND EXTRACT CONTAINING Ϝ-AMINOBUTYRIC ACID

摘要

[PROBLEMS] To provide novel methods of producing Ϝ-aminobutyric acid and an extract containing Ϝ-aminobutyric acid by using a lactic acid bacterium. [MEANS FOR SOLVING PROBLEMS] A method of producing Ϝ-aminobutyric acid which comprises using Lactobacillus reuteri and producing Ϝ-aminobutyric acid from glutamic acid or its salt. A method of producing an extract containing Ϝ-aminobutyric acid which comprises co-culturing lactic acid bacteria at least containing Lactobacillus reuteri together with a yeast in a medium containing glutamic acid or its salt and then obtaining an extract containing Ϝ-aminobutyric acid by subjecting the co-culture medium to solid-liquid separation.
