摘　　要：综述了近期在烃的微生物摄取机制方面的研究进展。对提高环境生物整治效果而言,微生物对非水溶性底物,尤其是烃的摄取机制是重要的课题。随着理论认识的深入和研究手段的丰富,在该领域已有了更多发现和结论。介绍了表面活性剂对烃摄取的影响,细胞表面性质的调整和烃的跨膜输送等方面的近期研究结果;同时,提供了细胞亚微结构分析,细胞趋化性等相关证据,指出了在该领域尚待解决的问题。Recent advance in researches of alkane uptake by microorganisms was reviewed. To improve efficiency of bioremediation, knowledge of mechanism of water-insoluble substrate, especially alkanes, uptake by microorganism is badly needed. Powered by novel ideas and advanced techniques, more findings and conclusions were reported. Effects of surfactants on uptake of alkane, adjustment on cell surface properties and transport of alkane into the cells were discussed in this review, at the same time, evidences from analyses of cell ultra-structure and researches on cell chemotaxis were cited. There are still some questions in this area should be taken into consideration.
