High temperature utilization of PAM and HPAM by microbial communities enriched from oilfield produced water and activated sludge.

ABSTRACT: Non-hydrolyzed polyacrylamide (PAM) and partially hydrolyzed polyacrylamide (HPAM) are commonly used polymers in various industrial applications, including in oil and gas production operations. Understanding the microbial utilization of such polymers can contribute to improved recovery processes and help to develop technologies for polymer remediation. Microbial communities enriched from oilfield produced water (PW) and activated sludge from Alberta, Canada were assessed for their ability to utilize PAM and HPAM as nitrogen and carbon sources at 50 °C. Microbial growth was determined by measuring CO₂ production, and viscosity changes and amide concentrations were used to determine microbial utilization of the polymers. The highest CO₂ production was observed in incuba
