| 摘 要： | 红球菌属是有机污染物降解的重要微生物之一。由于红球菌能够适应各种各样的底物环境,具有极强的有机溶剂耐受性和很宽的降解谱,同时它们还能通过产生表面活性剂和改变细胞表面组成结构来提升自身对于疏水性环境的适应能力,因此,红球菌在石油污染物降解及石油污染的生物修复等领域有着极其重要的应用价值。文章基于近年来在红球菌降解石油烃方面的研究进展,从红球菌适应疏水性环境的机制、石油烃中烷烃、环烷烃、芳香烃的降解途径等几个方面进行综述,同时对今后研究的方向进行了展望。 |

| Abstract: | Rhodococcus as a sort of microbial for organic compounds biodegradation with strong organic solvent tolerance and wide degradation spectrum,can adapt to various substrates,as well as promoting its adaption to hydrophobic surroundings by producing surfactants or changing cell surface composition and structure.Due to the characteristics, Rhodococcus acts extremely important roles in oil pollution bioremediation.Based on progress in petroleum hydrocarbon biodegradation by Rhodococcus,the adaption mechanism to hydrophobic environment,the degradation process of alkane, cycloparafin hydrocarbon and aromatics were reviewed.The prospect related to Rhodococcus in bioremediation in future was also proposed. |
| Keywords: | Rhodococcus oil pollution biodegradation progress |
