polyacrylamide, cationic polyacrylamide, anionic

polyacrylamide introduction： the polyacrylamide (pam) produced by hangrui is a water-soluble polymer, insoluble in most organic solvents, and has great flocculation result. it can reduce the frictional resistance between liquids. according to the ionic character, it can be divided into three types: anion, cation and non-ion.

How is polyacrylamide biodegradable?
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.
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 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.
