Reclassification of Anaerobaculum mobile, Anaerobaculum thermoterrenum, Anaerobaculum hydrogeniformans as Acetomicrobium mobile comb. nov., Acetomicrobium thermoterrenum comb. nov and Acetomicrobium hydrogeniformans comb. nov., respectively, and emendation of the genus Acetomicrobium

Abstract : Taking into account their 16S rRNA gene sequences, it appears that Acetomicrobium flavidum and the three Anaerobaculum species 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 since being validated later after the genus Acetomicrobium. The DNA G+C content of A. flavidum is 47.1 mol %, which is in the same order as that of the three Anaerobaculum species. All these bacteria have in common iso-C15:0 as their main fatty acid. Based on further phylogenetic, genetic, and chemotaxonomic studies, we propose Anaerobaculum mobile (= DSM 13181T = JCM 12221T), Anaerobaculum thermoterrenum (=DSM 13490T = ACM 5076T) and Anaerobaculum hydrogeniformans (= DSM 22491T =ATCC BAA-1850T) to 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.
