Biodegradation of Polyacrylamide and Its Derivatives | Environmental Processes - Springer

The biodegradation of PAM and its derivatives are initiated by the enzyme amidase, either under aerobic or anaerobic conditions, and are further degraded partially or completely by an array of different enzymes.

microbial degradation of polyacrylamide and the deamination product polyacrylate

Microbial degradation of polyacrylamide and the deamination product polyacrylate

open access Highlights ? 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. ?

Acidovorax PSJ13, a novel, efficient polyacrylamide-degrading bacterium by cleaving the main carbon chain skeleton without the production

Given the environmental challenge caused by the wide use of polyacrylamide (PAM), an environmental-friendly treatment method is required. This study demonstrates the role of Acidovorax sp. strain PSJ13 isolated from dewatered sludge in efficiently degrading PAM. To be specific, the strain PSJ13 can degrade 51.67% of PAM in 96 h (2.39 mg/(L h)) at 35 ¡ãC, pH 7.5 and 5% inoculation amount
