【摘要】 从长期受农药污染的土壤中分离得到一株能高效降解均三嗪类除草剂的菌株 ,命名为 FR,对其生理生化及降解特性进行了测定 ,结果表明 ,FR对于典型均三嗪化合物扑草净有很好的降解作用 ,最佳碳源为 8g/L的甘油 ;经 DEAE纤维素层析及苯基交联琼脂糖亲合层析纯化后酶活性提高近 30倍更多还原

【Abstract】 A superior strian, FR, which was isolated from soils exposed to repeated spills of herbicides, was studied on its physical and biochemical and degrading characters. The results showed that FR had a good degrading effect on pronutryne, a typical s triazine, its optimum carbon source was glycol whose concentration was 8g/L. The activity of enzyme purified by DEAE cellulose and Phenyl Sepharose chromatogram was improved up to 30 times.更多还原
