摘  要：
从福建省福农生化有限公司排污口的土壤中筛选到一株对乐果有较好降解效果的菌株阴沟肠杆菌,为了使该菌能更好的应用于乐果残留污染的治理当中,采用室内培养方法,对该菌降解乐果的作用因素进行研究。结果表明,菌降解乐果的最佳温度为35℃、pH为8.0、装液量50mL.250mL-1、摇床振数180r.min-1、C源为果糖、N源为酵母浸膏、接种量OD265为0.065、底物浓度为200mg.L-1,对应的降解率在28.84%～61.19%之间,采用L1(82×37)正交法及DPS数理统计得出Cu2+、Fe2+对菌降解乐果有显著的促进效果,Cd2+、Zn2+则在溶液中含量低水平时促进降解,高水平时抑制降解;Mg2+、Ba2+、Mn2+、Pb2+等离子对菌降解乐果无促进作用。

摘  要：
By using selective cultural media,Enterobacter closcae was isolated to degrade dimethoate from the soil around the pesticide fac-tory.The factors affecting the degradation of dimethoate by E.closcae were studied.The results showed that the optimum temperature for the degradation was 35 ℃ for the growth of the strain,the initial pH was 8.0,the conformable carbon source was fructose,the conformable nitro-gen source was the yeast extract,the inoculum's size was OD265:0.065,the density of dimethoate was 200 mg.L-1,the air supply was 50 mL.250 mL-1 volume in the cultural bottle with 180 r.min-1 speed in the rotated shaker,in which the degrading rates to dimethoate were ranged in 28.84%～61.19%.The L1(82×37)orthogonal test showed that the ion Cu2+ and Fe2+ could promote the strain to degrade dimethoate,and Cd2+、 Zn2+ could also promote it when it was at low level.However,Mg2+,Ba2+,Mn2+,Pb2+ had no effect on the degradation of dimethoate.
