摘要 以多氯联苯(3,3',4,4'-四氯联苯)为选择培养基,从污水处理厂生物处理过程的活性污泥中分离出2株能以3,3',4,4'-四氯联苯为唯一碳源的菌株,分别命名为J-4、J-5;观察2株菌的形态特征,并对其16S rRNA基因序列进行分析,构建了系统发育树。结果表明,J-4菌与红球菌属(Rhodococcus sp.)的细菌具有较高的序列同源性,J-5菌与鞘氨醇杆菌属(Sphingobacterium)的细菌具有较高的序列同源性。初步判定J-4为红球菌属(Rhodococcus sp.)的细菌,J-5为鞘氨醇杆菌属(Sphingobacterium)的细菌。本研究结果为多氯联苯的生物降解提供了理论依据,有利于多氯联苯降解菌库的充实和完善。
