Gamma-aminobutyric acid (GABA) is produced by Lactobacillus brevis using date residue fermentation. In this study, the GABA production method was improved, for which L. brevis strain JCM 1059T was the most efficient among the four L. brevis strains examined. This was presumably due to a difference in the expression level of the gene encoding glutamate decarboxylase that catalyzes GABA synthesis.Abbreviation: GABA: gamma-aminobutyric acid.

带有枣渣提取物的γ-氨基丁酸生产过程中短乳杆菌中两个谷氨酸脱羧酶基因的表达。

γ-氨基丁酸（GABA）是由短乳杆菌使用枣渣发酵产生的。在这项研究中，改进了GABA的生产方法，在所考察的4种短乳杆菌中，短乳杆菌JCM 1059T最有效。推测这是由于催化谷氨酸合成的谷氨酸脱羧酶编码基因的表达水平不同。缩写：GABA：γ-氨基丁酸。
