摘要
从胜利油田油井附近土壤中筛选到 1 株施氏假单胞菌(Pseudomonas stutzeri UP1),可把二苯并噻吩(DBT)降解成水溶性硫化物,静息细胞实验证实该菌株细胞内存在能够降解DBT的酶系,降解过程的某些中间产物及终产物与已知的Kodama 路线相同,表明此菌株对DBT的降解是以 Kodama 路线进行的.
A strain of Pseudomonas stutzeri UP1 was isolated from the soil of Shengli Oil Field. Dibenzothiophene (DBT) was degraded by this strain to water-soluble sulfide. Resting cell test proved that in the cell there existed enzymes capable to degrade DBT. Some intermediates and end products of DBT degradation were consistent with those of the wellknown Kodama course, indicating that DBT was degraded by this strain with the Kodama course.
