title: [Study on biodegradation of polyacrylamide].
abstract: Phanerochaete chrysosporium was introduced into biodegradation of polyacrylamide(PAM), and effects of glucose amount, pH, N concentration, Mn2+ concentration and biodegradation time on biodegradation of PAM were studied. Results show that Phanerochaete chrysosporium has special abilities of enzyme catalysis biodegradation of PAM. And the removal rate of PAM is 50%. Nitrogen limitation (NH4+ = 0.2 g/L) and Mn2+ concentration (Mn2+ = 0.017 5 g/L) are optima of producing PAM biodegradation enzyme.
