biodegradation of low molecular weight polyacrylamide under aerobic and anaerobic conditions: effect of the molecular weight cost

the biodegradation of polyacrylamide (pam) includes the hydrolysis of amino groups and cleavage of the carbon chain; however, the effect of molecular weight on the biodegradation needs further investigations. in this study, biodegradation of low molecular weight pam (1.6 × 106 da) was eva …

two strains of bacteria from oilfield slickwater and their performance in partially hydrolyzed polyacrylamide biodegradation sciencedirect,the characteristic peak around 3300 cm −1 of the biodegraded sample became broader and moved to low wavenumber, which indicated the hydrolysis of amide groups during biodegradation. two new characteristic peaks appeared at 1666 cm −1 and 1655 cm −1 after biodegradation, which were the characteristic absorption peaks of the carbonyl group.

biodegradation of anionic polyacrylamide mediated by laccase and amidase: docking, virtual mutation based on affinity and dft study rsc publishing

biodegradation of anionic polyacrylamide (hpam) by key enzymes, such as amidase and laccase, has been reported. however, the interaction details between hpam and enzymes are still unclear. here, docking was performed to demonstrate their binding modes and interactions. then, alanine (ala) scanning and satura
