To produce tomato juice with health-promoting functions, lactic acid bacteria (LAB) capable of converting l-glutamic acid in tomatoes into γ-aminobutyric acid (GABA) was screened from LAB stocks isolated from Japanese pickles. Lactiplantibacillus plantarum KB1253 was selected as the highest GABA producer among 74 strains of LAB stocks. gad gene expression and glutamic acid decarboxylation activity increased at low pH (3.0-3.5), whereas the growth decreased. Under optimal reaction conditions using resting cells as catalysts, this strain produced 245.8 ± 3.4 mM GABA. Furthermore, this strain produced 41.0 ± 1.1 mM GABA from l-glutamic acid in tomato juice under optimal fermentation conditions (pH 4.0, 20°Bx). This study may provide the basis for developing health-promoting functional foods rich in GABA from tomatoes and other agricultural products.
