16 S rRNA基因序列的三个先前描述的氨基酸发酵厌氧菌，月单胞菌acidaminovorans，'月单胞菌acidaminophila'和真杆菌acidaminophilum，进行了测定。这三种细菌都聚集在梭菌属和革兰氏阳性菌亚门的相关属中。嗜热菌S. Acidaminovorans，形成了一个单独的血统，并等距放置在Deshiosulfovibrio peptidovorans和Anaerobaculum thermoterrenum之间（相似性为85%），两者也形成了单一的血统。'S. Acidaminophila'与Clostridium quercicillum属第IX群成员相似性达90%，而E.嗜酸氨基梭菌与Clostridium litorale（相似性为96%）的亲缘关系较近，为第XI群的成员。根据本报告中的系统发育数据和以前发表的这些细菌的表型描述，建议S。嗜酸氨基酸菌被转移到一个新属，Thermanaerovibrio gen. nov.，将嗜酸氨基嗜热弧菌（Thermanaerovibrio acidaminovorans comb. nov.）和嗜酸氨基月形单胞菌（Selenomonasacidaminophila）转移到新属--Anaeromusa gen，nov.，作为嗜酸氨厌氧菌Anaeromusa acidaminophila comb，nov.将acidaminophilum作为一个新的分类单元是合理的，但在对聚类XI的所有成员的分类地位进行审查之前，不建议这样做。
16S rRNA gene sequences of three previously described amino-acid-fermenting anaerobes, Selenomonas acidaminovorans, 'Selenomonas acidaminophila' and Eubacterium acidaminophilum, were determined. All three were found to cluster within the Clostridium and related genera of the subphylum of the Gram-positive bacteria. The thermophile, S. acidaminovorans, formed an individual line of descent and was equidistantly placed between Dethiosulfovibrio peptidovorans and Anaerobaculum thermoterrenum (similarity of 85%), both of which also form single lines of descent. 'S. acidaminophila' was related to Clostridium quercicolum, a member of cluster IX, with a similarity of 90%, whereas E. acidaminophilum was closely related to Clostridium litorale (similarity of 96%) as a member of cluster XI. Based on the phylogenetic data presented in this report and the phenotypic descriptions of these bacteria published previously, it is recommended that S. acidaminovorans be transferred to a new genus, Thermanaerovibrio gen. nov., as Thermanaerovibrio acidaminovorans comb. nov. and 'Selenomonas acidaminophila' be transferred to it new genus, Anaeromusa gen, nov., as Anaeromusa acidaminophila comb, nov. Though the transfer of E. acidaminophilum to a new taxon is justified, this is not recommended until the taxonomic status of all the members of cluster XI has been reviewed.
