  • 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.
  • 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.
  • Does polyacrylamide decrease oxygen demand during the incubation of granules?
  • Furthermore, the chemical oxygen demand decreased during the incubation of the granules in the presence of polyacrylamide. Liquid chromatography–mass spectrometry (LC-MS) analysis showed that the main intermediate of degradation was polyacrylic acid, consisting of seven monomers ( Liu et al., 2012 ).
  • 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.
