Lactobacillus futsaii CS3, a New GABA-Producing Strain Isolated from Thai Fermented Shrimp (Kung-Som).

ABSTRACT: Kung-Som is a popular traditional Thai fermented shrimp product. It is rich in glutamic acid, which is the major substrate for the biosynthesis of gamma-aminobutyric acid (GABA) by lactic acid bacteria (LAB). In the present study, LAB from Kung-Som were isolated, screened for GABA formation, and the two isolates that transform glutamic acid most efficiently into GABA were identified. Based on the API-CHL50 fermentation profile and a phylogenetic tree of 16S rDNA sequences, strain CS3 and CS5 were identified as Lactobacillus futsaii, which was for the first time shown to be a promising GABA producer. L. futsaii CS3 was the most efficient microorganism for the conversion of 25 mg/mL monosodium glutamate (MSG) to GABA, with a maximum yield of more tha
