摘要：	从多年施用五氯硝基苯的栽参地土壤中分离出8株可降解五氯硝基苯的菌株，并对其降解效果进行了研究。结果表明：其中细菌B1、B2、真菌R、放线菌S1的降解效果最好，降解率分别为73．6％、81．0％、73．4％、72．0％。将这4株优势菌株制成复合菌剂，对复合菌剂中各组成菌种的生长情况及其对五氯硝基苯代谢效果的研究结果表明：复合菌剂A、B、C、D、F、G对五氯硝基苯的代谢能力强于单一菌株。

Abstract:	Eight strains that can degrade organic PCNB pesticides were isolated and selected from soil of grown panax which had been fertilized PCNB for many years. Their degradation capability to PCNB was studied. The results showed that the strains B_1,B_2, F_1 and S_1 had the significant effect. Ratio of degradation was 73.6%,81.0%,73.4% and 72.0%. Four strains that had better degradation capability were mixed to compare the degradation effect. The result showed that mixture strains had better degradation capability than simple strains and growth of every combined strains was not restrained.

Keywords:	pentachloro-nitrobenzene folosan (PCNB) degradation strain mixture strain
