从Frateuria aurantia（DSMZ 6220）中分离的主要脂质是异支化脂肪酸和藿烷家族的三萜类化合物，如细菌藿烷四醇和衍生的类藿烷，以及痕量的双辛烯和重排化合物，如蕨类-7-烯。研究了生长温度和收获细胞的生长阶段对该脂质指纹的影响。正如预期的那样，饱和化合物随温度的增加是脂肪酸组成的重要变化。脂肪酸组成在生长过程中也有显著变化。全局脂质指纹，至少包括PLFA和三萜类化合物被认为是一种工具，用于测量细菌细胞的应激状态。随着温度的升高，C-31羟基化类胡帕酸的含量增加，这是一个新的信息，值得关注和进一步研究，以更好地理解明显受环境变化调节的修饰的生理意义。(C)2004年，欧洲微生物学会联合会。Elsevier B.

The main lipids isolated from Frateuria aurantia (DSMZ 6220) are iso-branched fatty acids and triterpenoids of the hopane family like bacteriohopanetetrol and derived hopanoids, beside trace amounts of diploptene and rearranged compounds like fern-7-ene. The impact of the growth temperature and the growth phase in which cells were harvested on this lipid fingerprint was investigated. As expected, an increase of saturated compounds with temperature is the essential modification in the fatty acid composition. The fatty acid composition also varies significantly during the growth. Global lipid fingerprints, including at least PLFA and triterpenoids are suggested to be a tool for measuring the stress state of bacterial cells. Increasing amounts of C-31 hydroxylated hopanoids with a temperature increase is novel information which deserves attention and further investigation for a better comprehension of the physiological significance of modifications conditioned obviously by environmental changes.
