  • How is polyacrylamide biodegraded?
  • Both single microbial species as well as mixed populations have been investigated for degradation. 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.
  • Is polyacrylate more recalcitrant to biodegradation than amide?
  • The carbon backbone, polyacrylate, is more recalcitrant to biodegradation than the amide moieties. There are nevertheless reports on microbial growth with polyacrylamide and polyacrylate as the carbon sources.
  • Can polyacrylamide be partially hydrolysed to anionic copolymers?
  • For example, polyacrylamide can be partially hydrolysed to anionic copolymers consisting of acrylamide and acrylate. Cationic polyacrylamide can be produced in reactions of the amide groups with formaldehyde and a secondary amine, with so-called Mannich bases as the products.
  • Are polyacrylates recalcitrant to degradation?
  • Remaining polyacrylates are more recalcitrant to degradation. Polyacrylamide degradation has mainly been reported for aerobic bacteria. With fungi the degradation is initiated by secreted lignin degrading oxidases. Polyacrylamide may be degraded to acrylamide anaerobically, but not aerobically.
