Lactic Acid Bacteria-Derived γ-Aminobutyric Acid: From Targeted Screening and Biosynthesis to Functional Food Applications and Health Benefits
γ-Aminobutyric acid (GABA) is a non-proteinogenic amino acid that acts as a major signaling molecule across the nervous, cardiovascular, and immune systems. While GABA has historically been produced via chemical synthesis or plant extraction, microbial fermentation using lactic acid bacteria (LAB) provides a safe, sust...
