中文摘要：
从长期受农药污染的土壤中分离到1株高效杀螟硫磷降解菌株Burkholderia sp．FDS-1，它能以3-甲基-4-硝基苯酚（MNP）为唯一碳源和氮源进行生长．该菌能在9h内将0．6mmol·L^-1 MNP完全转化成邻甲基对苯二酚（MHQ），并能继续降解MHQ．该菌降解MNP的最适温度和pH分别为30℃和7．0，菌株降解MNP的速率和起始接种量呈正相关．降解MNP的酶为诱导酶．
英文摘要：
Strain Burkholderia sp. FDS-1 was isolated from long time pesticide polluted soil, which was capable of utilizing 3-methyl- 4-nitrophenol （MNP） as the sole carbon and nitrogen source to support its growth. It could transform 0.6mmol/L MNP into methylhydroquinone （MHQ） completely in 9h and continue to degrade MHQ. The optimal temperature and pH for the degradation were 30℃ and 7.0 respectively. The degradation speed correlated positively to the initial inoculation amount. The MNP degrading related enzyme in this bacterium was the inducible enzyme.
