摘要
以氯嘧磺隆为唯一碳源,从多年施用氯嘧磺隆的土壤中经富集和分离纯化获得了8株氯嘧磺隆降解菌。通过对其菌体和菌落形态的观察,确定其中有5株细菌,2株放线菌和1株真菌。采用玉米主根生长抑制率的生物测定法,对8株菌的氯嘧磺隆降解率进行测定,最终筛选出1株氯嘧磺隆高效降解放线菌B-4,其氯嘧磺隆降解率可达97.2%。
In this study,eight strains using chlorimuron-ethyl as the sole carbon source were isolated from soil that applied chlorimuron-ethyl for years.Through colony and thalli configuration observation,five strains of bacteria,two strains of actinomycetes and one strain of fungal were determined.By measuring chlorimuron-ethyl degradation efficiency using the bio-assay,one strain of actinomycetes B-4 with degradation efficiency of 97.2% was obtained.
