Özet
The aim of this study was to isolate lactic acid bacteria (LAB) from artisanal Turkish cheeses and to determine the strains potentially capable of producing high levels of gamma aminobutyric acid (GABA). A total of 507 LAB were isolated from 45 cheese samples. The cheeses exhibited a microbial diversity, consisting of 16 genera and 30 different species belonging to these genera. The most abundant species in all cheeses was Lacticaseibacillus paracasei. Only 40 of 507 isolates had the GAD gene, and all strains were genetically identified as Lactiplantibacillus plantarum. Two strains (134 and 255) produced GABA in high concentrations, in MRS broth (626.36 +/- 9.86 mg L-1) and skim milk (5.40 +/- 0.47 mg L-1), respectively. The results showed that most of the GABA-producing isolates, especially strains 255 and 134, could be used as starter cultures for the production of functional foods to reduce the risk of disease or improve certain physiological functions.
