Abstract: γ-polyglutamic acid(γ-PGA)is naturally occurring poly amino acids with characteristics of water solubility, biodegradability, edible and non-toxicity towards human, animals and the environment. Therefore, γ-Poly(glutamic acid)and its derivatives have been of interest in a broad range of industrial fields such as environment, medicine, food, cosmetics and feed additives. This paper focuses on the microbial synthesis of γ-PGA of related genes, synthesis mechanism and fermentation.

Key words: γ-polyglutamic acid, gene, mechanism, fermentation
