摘　　要：　从施用过五氯硝基苯(Pentachloronitrobenzene,PCNB)的土壤中分离得到高效放线菌菌株———金霉素链霉菌(Streptomycesaureofacients),它能够依靠共代谢作用还原五氯硝基苯.实验确定了该菌株的适宜生长条件:温度25℃～30℃,pH值为7 0.在该菌株的作用下,PCNB的降解加速,半衰期低于27d.One effective bacterial strain Streptomyces aureofacients which can highly reduce pentachloronitrobenzene by co-metabolism is isolated from the soil employed by PCNB.The growing conditions are optimized as follows from the experiment.Tempurature:25℃～30℃;pH 7.0～7.5.The rate of PCNB degradatron is faster under action of the bacterial strain.So the half-live of PCNB is less than 27 days.Pentachloronitrobenzene is transformed into pentachloraniline by reduction of the bacterial strain.
