Abstract:: The effects of various concentrations of glucose and Mn (Ⅱ) on degradation of sulfametoxydiazine sodium (SMD-Na) by Phanerochaete chrysosporium were investigated through batch experiments.The results showed that the degradation efficiency of SMD-Na and the fungal biomass were very low without glucose and increased with the rise glucose concentration from 3 g/L to 10 g/L.At the same time,the SMD-Na biodegradation had the positive relevance of manganese peroxidase (MnP) and lignin peroxidase (LiP).The removal efficiency of SMD-Na and MnP activity increased with the rise Mn(Ⅱ) concentration from 0.01 mmol/L to 0.1 mmol/L.However,the Mn(Ⅱ) concentration had no significant effect on LiP.
