  • Biodegradation of Polyacrylamide and Its Derivatives ...

    2017-5-4 · Saccharomyces cerevisiae was also reported to degrade 62% acrylamide at 30 °C (Akillioglu and Gökmen 2014 ). Although most of the pathways involved in biodegradation of PAM and its derivatives have been widely studied in bacterial strains, nothing has been reported on the degradation pathway by fungal strains.

    2019-4-1 · 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.
