一株枯草芽孢杆菌对氯氰菊酯降解率的测定

Determination of Cypermethrin Degradation Rate byBacillussubtilis

从重庆市潼南区某果园土壤中分离到1株能够降解氯氰菊酯的枯草芽孢杆菌(Bacillussubtilis),编号A-1。通过高效液相色谱的方法测定A-1对氯氰菊酯的降解率,结果表明,A-1对100 mg/L氯氰菊酯120 h降解率为30.25%,对氯氰菊酯有明显的降解作用。

From sichuan orchard soil were isolated from 1 strain degradation of cypermethrin bacteria A-1.The degradation rate of cypermethrin by A-1 was determined by HPLC. The results show that A-1 to 100 mg/L cypermethrin 120 h degradation rate for 30.25%.It has obvious degradation effect on cypermethrin.
