Taking into account their 16S rRNA gene sequences, it appears tha Acetomicrobium flavidum and the three species of the genus Anaerobaculum described so far belong to the same phylogenetic clade with high levels (>95 %) of similarity. In this respect, these three Anaerobaculum species should be reclassified within the genus Acetomicrobium , which has priority over the genus Anaerobaculum , which was validated since the genus Acetomicrobium . The DNA G+C content of Acetomicrobium flavidum is 47.1 mol%, which is of the same order as that of the three Anaerobaculum species. All these bacteria have in common iso-C 15 : 0 as their main fatty acid. Based on further phylogenetic, genetic and chemotaxonomic studies, we propose tha Anaerobaculum mobile ( = DSM 13181 T = JCM 12221 T ), Anaerobaculum thermoterrenum ( = DSM 13490 T = ACM 5076 T ) and Anaerobaculum hydrogeniformans ( = DSM 22491 T = ATCC BAA-1850 T ) be reclassified as Acetomicrobium mobile comb. nov., Acetomicrobium thermoterrenum comb. nov. and Acetomicrobium hydrogeniformans comb. nov., respectively. The four bacterial species belong to the phylum Synergistetes .
