【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7 h 内对50 mg/L MP 的降解率为85％, 对50 mg/L PNP 的降解率为99％,测定条件为：pH7．5,温度30℃,接种量20％．更多还原

【Abstract】 From polluted water of Huayang pesticide plant,isohted 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 degradabihty in detail,the removal rate of L-W was 85 percents when the concentration of mdthylparathion was 50mg/L and 99 percents when the concentration of ρ-nitrophenol was 50 mg/L respectively in 7 hours,the determine condition was:pH value 7.5,temperature 30 degree,inoculation quantity 20 percents.更多还原
