Two bacteria capable of efficiently degrading atrazine were isolated from soil, and named ATLJ-5 and ATLJ-11. ATLJ-5 and ATLJ-11 were identified as and , respectively. The degradation efficiency of atrazine (50 mg/L) by strain ATLJ-5 can reach about 98.6% after 7 days, and strain ATLJ-11 can reach 99.6% under the same conditions. The degradation of atrazine is faster when two strains are used in combination. Adding the proper amount of fresh soil during the degradation of atrazine by these two strains can also increase the degradation efficiency. The strains ATLJ-5 and ATLJ-11 have high tolerance to atrazine, and can tolerate at least 1000 mg/L of atrazine. In addition, the strains ATLJ-5 and ATLJ-11 have been successfully made into a microbial agent that can be used to treat atrazine residues in soil. The degradation efficiency of atrazine (50 mg/kg) could reach 99.0% by this microbial agent after 7 days. These results suggest that the strains ATLJ-5 and ATLJ-11 can be used for the treatment of atrazine pollution.
从土壤中分离出两种能够高效降解莠去津的细菌,分别命名为ATLJ - 5和ATLJ - 11。ATLJ - 5和ATLJ - 11分别被鉴定为 和 。菌株ATLJ - 5对莠去津(50毫克/升)的降解效率在7天后可达到约98.6%,在相同条件下菌株ATLJ - 11可达到99.6%。当两种菌株联合使用时,莠去津的降解速度更快。在这两种菌株降解莠去津的过程中添加适量新鲜土壤也可提高降解效率。菌株ATLJ - 5和ATLJ - 11对莠去津具有高耐受性,能够耐受至少1000毫克/升的莠去津。此外,菌株ATLJ - 5和ATLJ - 11已成功制成可用于处理土壤中莠去津残留的微生物制剂。该微生物制剂对莠去津(50毫克/千克)的降解效率在7天后可达99.0%。这些结果表明菌株ATLJ - 5和ATLJ - 11可用于处理莠去津污染。
