摘要
以二苯并噻吩(DBT)为模型化合物,筛选到一株能有效降解DBT的菌株,根据其菌落的形态特征、生理生化特征和分子生物学鉴定方法,确定其为Pseudomonas stutzeri UP-1。该菌株对DBT具有较强的降解能力,降解终产物为水溶性物质。通过对降解产物的分析,初步推断DBT的降解符合Kodama机理。
Dibenzothiophene (DBT) was used as a model compound. A bacteria strain, which can degrade dibenzo-thiophene efficiently, was obtained. This strain was identified as Pseudomonas stutzeris UP-1 according to its morphological, physiological and biochemical characters, and 16S rDNA sequence. The strain exhibits strong degradation capacity of DBT, and the end product of degradation is a kind of soluble compound. After the analysis of product of DBT degradation, it was deduced that the degradation of DBT by Pseudomonas stutzeri UP-1 is in accordance with the Kodama mechanism.
