英文摘要 | A bacterial strain, CN similar to 3, was isolated from petroleum-contaminated sediment in Bohai Bay, China. Morphological, physiological and phylogenetic analyses indicated that the strain belonged to the genus Dietzia. It was capable of utilizing a wide range of alkanes (C-14-C-31), aromatic compounds and crude oil as the sole carbon and energy sources. The bacterium showed high degradation rate (>80%) of the saturated hydrocarbons of crude oil in the pH range of 6-9. The degradation rate was hardly affected at a NaCl concentration up to 85 g L-1, indicating that the strain can tolerate high salinities. The real-time quantitative Polymerase Chain Reaction (PCR) results showed that the CYP153 genes could be significantly induced by C-14, C-15, C-16, C-26 and pristane, whereas the transcription level of alkB gene was increased moderately with C-14, C-15, C-16, C-26 and pristane induction condition. A high degradation extent, wide substrate range and facile conditions enhanced the potential for this bacterial strain to be used in the bioremediation of crude oil pollution. (C) 2017 Elsevier Ltd.
