In the past workers have isolated several pseudomonad strains which have been used for studies of anaerobic aromatic metabolism. The best studied of these strains are strains KB 740T (T = type strain) and K 172T. The taxonomic positions of these two organisms were determined by classical methods, including experiments to determine substrate spectrum, quinone type, and total fatty acid composition. Our results clearly excluded these strains from the authentic genus Pseudomonas, which belongs to the gamma subclass of the Proteobacteria. Instead, the properties of these organisms indicated that they belong to the beta subclass of the Proteobacteria. The sequences of the 16S ribosomal DNA genes confirmed this conclusion and indicated that strain K 172T represents a new species of the genus Thauera, Thauera aromatica, and that strain KB 740T represents a new species of the genus Azoarcus, Azoarcus evansii.
过去，研究人员分离出了几种假单胞菌菌株，这些菌株已被用于厌氧芳香族化合物代谢的研究。其中研究得最深入的菌株是KB 740T（T = 模式菌株）和K 172T。这两种微生物的分类地位是通过经典方法确定的，包括测定底物谱、醌型和总脂肪酸组成的实验。我们的结果明确将这些菌株排除在真正的假单胞菌属之外，假单胞菌属属于变形菌门的γ亚纲。相反，这些微生物的特性表明它们属于变形菌门的β亚纲。16S核糖体DNA基因序列证实了这一结论，并表明K 172T菌株代表陶厄氏菌属的一个新物种，即芳香陶厄氏菌，而KB 740T菌株代表偶氮弧菌属的一个新物种，即埃文斯偶氮弧菌。
