Abstract
Abstract 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
