- What is biodegradation of hydrolyzed polyacrylamide?
- Biodegradation of hydrolyzed polyacrylamide by the combined expanded granular sludge bed reactor-aerobic biofilm reactor biosystem and key microorganisms involved in this bioprocess Bioresour. Technol., 263 ( 2018), pp. 153 - 162
- 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
- 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 bioremediated?
- Although polyacrylamide (PAM) and its derivatives have many useful applications, their release in nature can have impacts on the environment and human health, thus bioremediation approaches for residual PAM are urgently needed.
