摘　　要：耐辐射奇球菌对辐射、干燥、氧化剂等极端条件具有极强的抵抗能力,其特有的脂类之一是极性磷酸糖脂,磷酸糖脂含有烷基胺取代基团,烷基胺由脂肪酸衍生而来。脂类的组成特征是奇球菌属的分类标准之一。本文概述了耐辐射奇球菌的主要特征,介绍了已发现的特种极性脂类、分类学意义,以及特种脂类与其抗性机制可能关系的研究进展,并对耐辐射奇球菌特种脂类的应用前景进行展望。Deinococcus radiodurans is extremely resistant to radiation, desiccation, oxidizing agents and other extreme conditions. One of the unique lipids in Deinococcus radiodurans is the polar lipid phosphoglycolipid with alkylamine as the maincomponent. Alkylamine derived from fatty acids. The composition characteristic of lipids is one of the classification criterias of Deinococcus. This article provided an overview of the main features of the Deinococcus radiodurans and introduced special polar lipids that have been found as well as the taxonomy significances of such lipids. The research progress of the relationship between lipids and their resistance mechanisms and the prospects of special lipids in Deinococcus radidurans have also been discussed.
