摘要
考察了两组厌氧富集培养系对苄嘧磺隆(BSM)的厌氧降解情况,结果表明,厌氧颗粒污泥稳定培养系的降解效果略好于农药污泥稳定培养系;随着BSM浓度的增加,农药污泥稳定培养系的降解率逐步增加,而厌氧颗粒污泥稳定培养系的降解率则递减;温度的升高有利于提高两组厌氧培养系的降解率。鉴定结果表明:两种稳定培养系中占据优势菌群的门均为Spirochaetes、Bacteroidetes、Synergistetes、Euryarchaeota。
Two stable anaerobic culture systems were obtained to degrade the bensulfuron methyl(BSM).The degradation rate of BSM by the stable culture system from anaerobic granular sludge was slightly higher than that from the pesticide factory sludge.As the concentration of BSM increased,the degradation rate of BSM in the pesticide factory sludge was accelerated,while the degradation rate of BSM in anaerobic granular sludge was restrained.In addition,the increase in temperature was beneficial to the microorganism degradation.The main phylums in these two stable anaerobic culture systems were Spirochaetes,Bacteroidetes,Synergistetes,Euryarchaeota,respectively.
