Bacterial production of poly-γ-glutamic acid and evaluation of its effect on the viability of probiotic microorganisms
Poly-γ-glutamic acid (γ-PGA) is a naturally occurring biopolymer made up of repeating units of glutamic acid and can be potentially used for multiple applications. This study compared the production of γ-PGA by eight bacteria (B. subtilis 23856, B. subtilis 23857, B. subtilis 23858 B. subtilis …

Selection of bacterial species from wastewater for potential production of poly (γ-glutamic acid): isolation, characterisation and growth kinetics
… such as the production of alcohols, organic acids and polymers. The nutrient loads in municipal wastewaters are dilute, but add up to significant daily loads because of the massive volumes generated in urban populations. The effluent of most wastewater treatment plants in South Africa is …

STUDIES ON NATURAL AND EDIBLE BIOPOLYMERS. ISOLATION, CHARACTERIZATION AND CHEMICAL MODIFICATIONS OF POLY(Γ-GLUTAMIC ACID) (Γ-PGA) FROM BACILLUS SUBTILIS
Poly(γ-glutamic acid) (γ-PGA) is a unusual anionic, water-soluble homopolyamide composed of D- and/or L-glutamic acid monomers, connected by amide bonds between α-amino and γ-carboxyl groups, mainly produced by Gram-positive bacteria of the genus Bacillus. γ-PGA is hygroscopic and water-soluble; in …

Bacterial poly-gamma-Glutamic Acid (y-PGA) - a promising biosorbent of heavy metals
Poly-γ-glutamic acid (γ-PGA) is a biopolymer made up of repeating units of L-glutamic acid, D-glutamic acid or both. γ-PGA is water soluble, non-toxic and biodegradable, and can be used safely in a variety of applications that are increasing rapidly. This study investigated the production of HMW …

The role of γ-polyglutamic acid in a circular economy: cost-effective production and wide-ranging applications of a bio-derived, biodegradable, and nonimmunogenic biomaterial
… as backbones of biodegradable constructs. Poly-γ-glutamic acid (γ-PGA) is an anionic pseudo polypeptide produced by several microorganisms, especially members of the Bacillus species. γ-PGA is synthesised through several enzymes and complexes which racemise and polymerise L- glutamic acid …
