对 33 个厌氧革兰氏阴性杆菌属的物种的细胞脂肪酸谱进行了测定,并被证实是一种有用的分类工具。大多数属可以通过目视检查它们的轮廓来区分。视觉上最难区分的三个属对(拟杆菌属和普雷沃氏菌属、梳状单胞菌属和巨单胞菌属、以及丝氨酸属和双歧杆菌属)以及这些属的物种通过 MIDI (Microbial ID, Inc.) 识别系统进行区分。细胞脂肪酸谱的相似性可能与其他表型特征的相似性相关,但更常见的是没有其他明显的表型关系。尽管培养基成分可能不会改变某些物种检测到的成分或检测到的成分之间的比例,但相同的培养基变化可能会导致其他物种获得的概况存在巨大差异。因此,如果工作人员希望比较不同分类单元的概况,则必须使用相同的文化和分析条件。
Cellular fatty acid profiles were determined for species in 33 genera of anaerobic gram negative bacilli and were confirmed to be a useful taxonomic tool. Most of the genera could be differentiated by visual inspection of their profiles. The three genus pairs that were most difficult to distinguish visually (Bacteroides and Prevotella, Pectinatus and Megamonas, and Serpulina and Bilophila) and the species of these genera were differentiated by the MIDI (Microbial ID, Inc.) identification system. Similarities in cellular fatty acid profiles may be correlated with similarities in other phenotypic characteristics, but more often there is no other obvious phenotypic relationship. Although medium components may not change the constituents detected or the ratios among the constituents detected for some species, identical medium changes may result in vast differences in the profiles obtained with other species. Thus, if a worker wishes to compare profiles of various taxa, it is essential that the same cultural and analytical conditions be used.
