Degradation of diuron [3-(3,4-dichlorophenyl)-1,1-dimethyl-urea] by microorganisms obtained from pond water and sediment was determined under aerobic conditions. Enrichment procedures were used to isolate cultures capable of degrading the herbicide. Several mixed fungal/bacterial and mixed bacterial cultures were isolated that could degrade diuron. The mixed cultures degraded 67-99% of the added diuron forming from six to seven products which were separated via TLC. The major degradation product detected in most culture extracts was 3,4-dichloroanaline. Other identified products formed were 3-(3,4-dichlorophenyl)-1-methyl-urea and 3-(3,4-dichlorophenyl)urea.
在有氧条件下测定了从池塘水和沉积物中获得的微生物对敌草隆[3-(3,4-二氯苯基)-1,1-二甲基脲]的降解情况。采用富集培养法分离能够降解该除草剂的培养物。分离出了几种真菌/细菌混合培养物和细菌混合培养物，它们能够降解敌草隆。这些混合培养物降解了67%-99%添加的敌草隆，形成了六到七种产物，这些产物通过薄层层析法进行了分离。在大多数培养物提取物中检测到的主要降解产物是3,4-二氯苯胺。形成的其他已鉴定产物有3-(3,4-二氯苯基)-1-甲基脲和3-(3,4-二氯苯基)脲。
