  • 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.
  • How are polyacrylamides deaminated to polyacrylates?
  • Polyacrylamides are first deaminated to polyacrylates by microbial amidases. 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.
  • 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.
  • Can polyacrylamide be degraded in fungi?
  • 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. Polyacrylamides are widely applied for instance in wastewater treatment, papermaking, oil recovery and mining.
