- 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.
- Does polyacrylamide biodegradation accumulate acrylamide monomers?
- The biodegradation did not accumulate acrylamide monomers. Based on the SDS-PAGE and N -terminal sequencing results, the PAM amide groups were converted into carboxyl groups by a PAM-induced extracellular enzyme from the aliphatic amidase family. Keywords: polyacrylamide, biodegradation, dewatered sludge, microorganisms 1. Introduction
- How does polyacrylamide biodegradation affect the fate of related polyacrylic acid?
- Polyacrylamide copolymers, either anionic or cationic, are potentially quickly converted to corresponding polyacrylate salts by deamination or hydrolysis. Therefore, biodegradation of related polyacrylic acid (or related salts) provides insights in polyacrylamide biodegradation and their fate.
