【摘要】 为探讨六氯苯在特定环境下的可生物降解性,从武汉某化工厂排水沟底泥中分离出4株能以六氯苯为唯一碳源和能源生长的厌氧降解菌,并对单菌株和混合菌株降解六氯苯的能力进行了比较,发现混合菌株比单菌株对六氯苯有更好的降解能力.同时对混合菌群降解六氯苯的最适条件进行了研究,确定了混合菌群降解六氯苯的最适条件为pH值7.0、温度30℃、六氯苯浓度为3mg.L-1.更多还原

【Abstract】 In order to research the biodegradable characterstics of hexachlorobenzene（HCB）,four anaerobic bacteria strains that can grow with HCB as the sole carborn and energy source were isolated from the sewage sludge in barrel drain of a chemical plant in Wuhan and applied to degrade HCB.Comparing with single bacteria,we found mixed bacteria had better degradation capability.At the same time,the best condition of mixed bacteria degradation has been studied;and the best condition has been confirmed as: pH = 7.0,temperature 30℃,HCB density 3 mg·L^-1.更多还原
