Does GH protect polyacrylamide from environmental degradation?

The results of these studies suggest that polyacrylamide can degrade to acrylamides by thermal and photolytic effects, that changes in pH do not promote the depolymerization of polyacylamide, and that GH does protect polyacRYlamide and acrieslamide from environmental degradation. … …

How is polyacrylamide cleaved?

High-molecular-weight PAM was partly cleaved to small molecular oligomer derivatives and part of the amide groups of PAM had been converted to carboxyl groups by a PAM-induced extracellular enzyme from the aliphatic amidase family. Chemical Degradation of Polyacrylamide during Hydraulic Fracturing.

Can high molecular weight Pam be used for degradation?

This paper provides a short review of current applications of high molecular weight PAM, including the potential for PAM degradation by chemical, mechanical, thermal, photolytic, and biological processes.

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.

What is a high molecular weight polyacrylamide (PAM)?

… High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.

Can acrylamide be degraded?

The concentration of acrylamide that can be degraded and the end products depend on the bacterial strain. The majority of the strains degraded acrylamide to acrylic acid and other derivatives including ammonia, carboxylic acids and carbon dioxide, while others showed a complete acrylamide degradation to CO 2 and H 2 O (Table 1).
