降解菌株BY-6的分离及其降解性能研究
Isolation and Biodegradation Characteristics of a Bacterium Capable of Degrading Carbendazim
摘要
Abstract
[Objective] To isolate bacterium strains which could degrading carbendazim in soil and study the biodegradation characteristics of bacterium strains. [ Method] A bacterium YB-6 was screened and isolated from the carbendazim polluted soil. The effect of some factors on its biodegradation characteristics in vitro were studied,such as initial pH,culture temperature,inoculums size,extra carbon source,nitrogen source and initial concentration of carbendazim. [ Result] The results showed that bacterial strain YB-6 could grow by using carbendazim as the sole carbon source. It could degrade 55% of 100 mg/L carbendazim in mineral culture medium in 5 d, but could degrade 90% by adding 0.5% peptone as nitrogen source. The degradation property of carbendazim by BY-6 is good and the optimal pH and culture temperature for biodegradation are 7.0 and 30 ℃ respectively. The biodegradation speed was related positively to initial inoculums size.关键词
