Description: Poly-γ-glutamic acid (γ-PGA) is an unusual anionic homopolyamide made from d-and l-glutamic acid units connected through amide linkages between α-amino and γ-carboxylic acid groups. Furthermore, due to the γ-linkage of its component glutamate residues, γ-PGA is resistant to proteases that cleave α-amino linkages. Initially discovered in 1937 by Bruckner and co-workers as part of the capsule of Bacillus anthracis, γ-PGA has since been found in species from all three domains of life (archaea, bacteria, and eukaryotes). More importantly, as a biodegradable, water-soluble, edible, and non-toxic biopolymer, γ-PGA and its derivatives can be used safely in a wide range of applications including as thickeners, humectants, bitterness-relieving agents, cryoprotectants, sustained release materials, drug carriers, heavy metal absorbers, and animal feed additives.
