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.

Can acrylamide be biodegraded?

Biodegradation of PAM and its derivatives has been studied only in the last two decades, with most emphasis on acrylamide biodegradation. Microorganisms have been shown to utilize, not only acrylamide, but also PAM and its derivatives as the sole source of nitrogen and/or carbon under aerobic as well as anaerobic conditions.

Is polyacrylate recalcitrant to biodegradation?

Although the remaining polyacrylate is more recalcitrant to biodegradation than the amide group, there are reports on degradation of polyacrylate by aerobic fungal, aerobic and anaerobic bacteria (Nyyssölä and Ahlgren, 2019).

Are polyacrylamide flocculants biodegradable?

What is a polyacrylamide & oligomer?

Polyacrylamide (PAM) & oligomers PAM is a water-soluble, odorless, white synthetic linear polymer with the repeating formula (-CH 2 CHCONH 2 -), and its monomer used is AM. Its molecular weight (MW) of PAM ranges from 10 5 to >10 7 Da, with a length of up to six million monomer units.

Does acrylamide degradation change the structure of long chain Pam?

FT-IR analysis to elucidate the change of the structure of long chain PAM after degradation showed that the amido groups of the PAM were picked off by the microorganisms from the main chain of the PAM. Metabolism products other than acrylamide were formed in the degradation.
