摘要: 从农药厂污水处理系统中分离到 1株降解甲基一六O五 (O ,O-二甲基 -O- 对硝基苯基 -硫代磷酸酯 ,简称MP)的芽胞杆菌 ,初步鉴定为蜡状芽胞杆菌 (Bacillus cereus)J5。J5能够高效降解MP ,但它不能利用MP作为唯一碳源生长 ,其代谢方式可能为共代谢。在有葡萄糖作为碳源的条件下 ,J5可以高效转化MP ,其转化效率可达 95 %以上。用薄层层析、紫外扫描和液相色谱法初步研究了J5对MP的降解性能及相关降解产物。 AbstractFilter('ChDivSummary','ChDivSummaryMore','ChDivSummaryReset');

Abstract: From the wastewater treatment system of a pesticide plant, a Bacillus strain was isolated, capable of efficiently degrading methyl parathion (MP).It is preliminarily identified as Bacillus cereus J5.The bacteria,however,do not live on MP as the sole carbon and energy source.Experiment results suggest that J5 degrades MP by way of co metabolism.Growing in the medium with glucose as its carbon source, J5 can degrade MP by over 95%.Rate and metabolites of the degradation of MP by J5 were studied by means of TLC,ultra violate scanning and HPLC.

Key words: biological degradation, methyl parathion, co-metabolism
