Study on biodegradation of polyacrylamide
聚丙烯酰胺生物降解研究

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+=0.2g/L) and Mn2+ concentration(Mn2+=(0.0175)g/L) are optima of producing PAM biodegradation enzyme.
