The Screening and Identification of LAB Strains Isolated from Traditional Dairy Products with γ-aminobutyric Acid Producing and Optimizing Their Fermentation Conditions
9 LAB strains with relative high production ofγ-aminobutyric acid were screened from 180 strains isolated from traditional fermented dairy products using Thin Layer Chromatography (TLC) and High Performance Liquid Chromatography (HPLC). They were WH11-1(2.477g/L), M10-4-3(1.405g/L), WZ20-2(1.132g/L),WZ1-2(1.115 g/L), M11-3(1.006g/L),S1-1(0.581g/L), M5-1-1(0.310 g/L), M11-2-1(0.225 g/L)and M11-1(0.211 g/L).
According to the traditional morphological characters, physiological and biochemical prope...
