Isolation of Biodesulfurization Bacteria Pseudomonas stutzeri UP-1 for Petroleum / 微生物学通报

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.
