Production, Characterization, and Applications of Microbial Poly-γ-Glutamic Acid

Abstract

Poly γ-glutamic acid is a promising biodegradable polymer from bacterial sources with intense applications in the field of medicine, wastewater treatment, food and cosmetics, etc. In the production process, the yield of polygamma glutamic acid varies with the various parameters like nutrient requirements, culture conditions, and the bacterial strains used for the production and the mode of fermentation. Industrial scale production of this high value-added product is not still feasible because of its high production cost. Due to its commercial interest, the cost-effective process for production, efficient recovery, and purification are the current area of interest. Here, main focus is on the production, purification, characterization, and applications of PGA from bacterial sources.
