Abstract

Four strains belonging to the genus Bacillus, capable of degrading polychlorinated biphenyls (PCB), were isolated by screening the collection strains of soil bacteria, degrading a organochlorine pesticide, hexachlorocyclohexane (HCCH). A method for production of tritium-labeled PCB was developed. Consumption and degradation of PCB by the soil bacterial strains selected were studied using tritium-labeled PCB and GLC. It was demonstrated that PCB are degradable both in culture media and under in model soil samples.

摘要

通过筛选土壤细菌的收集菌株，分离出了4株属于芽孢杆菌属、能够降解多氯联苯（PCB）的菌株，这些菌株还能降解有机氯农药六氯环己烷（HCCH）。开发了一种生产氚标记多氯联苯的方法。使用氚标记的多氯联苯和气相色谱法研究了所选土壤细菌菌株对多氯联苯的消耗和降解情况。结果表明，多氯联苯在培养基和模拟土壤样品中均可降解。
