title: Bioconversion Using Lactic Acid Bacteria: Ginsenosides, GABA, and Phenolic Compounds.
abstract: Lactic acid bacteria (LAB) are used as fermentation starters in vegetable and dairy products and influence the pH and flavors of foods. For many centuries, LAB have been used to manufacture fermented foods; therefore, they are generally regarded as safe. LAB produce various substances, such as lactic acid, β-glucosidase, and β-galactosidase, making them useful as fermentation starters. Existing functional substances have been assessed as fermentation substrates for better component bioavailability or other functions. Representative materials that were bioconverted using LAB have been reported and include minor ginsenosides, γ-aminobutyric acid, equol, aglycones, bioactive isoflavones, genistein, and daidzein, among others. Fermentation mainly involves polyphenol and polysaccharide substrates and is conducted using bacterial strains such asStreptococcus thermophilus, Lactobacillus plantarum,andBifidobacteriumsp. In this review, we summarize recent studies of bioconversion using LAB and discuss future directions for this field.
