  • 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.
  • 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.
  • Can cationic polyacrylamides be used to purify industrial waste water?
  • The use of anionic, cationic as well as non-ionic polyacrylamides in purification of industrial waste waters have been reported ( Lee et al., 2014 ). In the papermaking industry, anionic and cationic polyacrylamides are used as aids for improving the retention of fillers, sizing agents and fine particles.
  • Does biological filtration improve polyacrylamide biodegradation?
  • Freedman, D. E. et al. Biologically active filtration for fracturing flowback and produced water treatment. J. Water Process Eng. 18, 29–40 (2017). Dai, X. et al. Waste-activated sludge fermentation for polyacrylamide biodegradation improved by anaerobic hydrolysis and key microorganisms involved in biological polyacrylamide removal.
