Abstract:[目的]考察Enterobacter sp.LY402在好氧条件下对氯丹的降解能力.[方法]将多氯联苯高效降解菌株Enterobacter sp.LY402运用到氯丹的好氧降解中.系统考察了LY402在好氧条件下降解过程的影响因素.[结果]在不加入其他碳源的情况下,对1.0 mg/L氯丹混合物的4 d降解率达到94%,对于浓度高达10.0 mg/L氧丹混合物总降解率也能达到61%以上.降解体系的温度和pH值对氯丹的好氧降解率有一定影响,pH值5.0~8.0,温度30~40℃对氯丹的好氧降解有利.[结论]Enterobacter sp.LY402具有很强的好氧降解氯丹的能力.
