Fig. 4From: High temperature utilization of PAM and HPAM by microbial communities enriched from oilfield produced water and activated sludgeViscosity measured in microbial enrichments derived from a PW and b sludge amended with PAM or HPAM as a N source at 50 °C. Viscosity was measured at 40 °C and 90 rpm. Error bars indicate standard deviations of triplicate samplesBack to article page
