Poly-γ-glutamic acid (γ-PGA) is a natural, biodegradable and water-soluble biopolymer of glutamic acid. This review is focused on nonrecombinant microbial production of γ-PGA via fermentation processes. In view of its commercial importance, the emphasis is on L-glutamic acid independent producers (i.e. microorganisms that do not require feeding with the(More)
Poly-γ-glutamic acid (γ-PGA), one type of amino acid polymers, consists of D-and L-glutamic acids linked with amide bonding between α-amino and γ-carboxylic acids. Naturally, γ-PGA could be biodegradable polymer and water-solubleapplied in various industries such as food, cosmetics, and pharmaceutical industries. Variation of initial L-glutamic acid(More)
