biodegradation of polyacrylamide and its derivatives

Biodegradation of Polyacrylamide and Its Derivatives

The biodegradation of PAM and its derivatives are initiated by the enzyme amidase, either under aerobic or anaerobic conditions, and are further degraded partially or completely by an array of different enzymes.

Isolation and Characterization of Polyacrylamide-Degrading

The microbial biodegradation of PAM has long been studied. Previous studies suggested that microorganisms are able to degraded and utilized PAM as a nitrogen source in both aerobic and anaerobic environments [13,14]. Microorganisms produce a polyacrylamide induced amidase to deaminate PAM .

microbial degradation of polyacrylamide and the deamination

Microbial degradation of polyacrylamide and the deamination

Biodegradation of polyacrylamide begins with amidase catalysed deamination of polyacrylamide to ammonia and polyacrylate. The liberated ammonia is then used as a nitrogen source for growth by the microbes. The carbon backbone, polyacrylate, is more recalcitrant to biodegradation than the amide moieties.

Bioremediation Technology: A Cumulative Study on Microbial

Microbial bioremediation is defined as a process to degrade, break down, or transform hazardous contaminants into less toxic or nontoxic forms by either naturally occurring or genetically engineered microbes or microbial consortia, thereby eliminating contaminants from the environment (Agrawal and Verma 2020a; Agrawal et al. 2020a ).
