摘要:
通过分批试验研究了葡萄糖与二价锰离子在黄孢原毛平革菌降解磺胺-5-甲氧基嘧啶钠(SMD-Na)中的作用.结果表明:未添加葡萄糖时,SMD-Na的去除率和生物量极低,当葡萄糖质量浓度在3～10g/L时,两者随之增加,同时,SMD-Na的去除率与锰过氧化物酶活(MnP)和木质素过氧化物酶活(LiP)变化具有正相关性.当二价锰离子初始浓度为0.01 ～0.1 mmol/L时,SMD-Na的去除率和MnP酶活随着锰离子浓度增加而增大,锰离子浓度对LiP酶活没有显著影响.
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.
