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
Microbial products have long been investigated for their potential 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 …

The development and performance of anodic biofilms in microbial fuel cells
Microbial fuel cell (MFC) systems capable of both treating wastewaters and recovering energy have the potential for successful scale-up as a low carbon technology. These systems utilize microorganisms residing in biofilms as biocatalytic agents in the conversion of reduced substrates to electrical …
