摘　　要：从生产甲基对硫磷的华阳农药厂污水暴气池中,分离到1株能以甲基对硫磷及其降解中间产物对硝基苯酚为惟一碳源生长,且能够将其彻底降解为CO2和H2O的细菌L-W,经鉴定,为节杆菌属(Arthrobacter sp).用气相色谱法和分光光度计法深入研究了L-W的降解性能.它7h内对50mg/LMP的降解率为85%,对50mg/LPNP的降解率为99%,测定条件为:pH7.5,温度30℃,接种量20%.From polluted water of Huayang pesticide plant,isolated a L-W strain which can grow with methylparathion,ρ-nitrophenol which produced during degradation as the sole source of carbon,and turn them to carbon dioxide and water,it was identified as Arthrobacter sp.By gas chromatography and spectrophotometer,studied L-W s degradability in detail,the removal rate of L-W was 85 percents when the concentration of melthylparathion was 50mg/L and 99 percents when the concentration of ρ-nitrophenol was 50 mg/L respect...
