Genome-based reclassification of Bacillus acidicola, Bacillus pervagus and the genera Heyndrickxia, Margalitia and Weizmannia

In the present study, the taxonomic positions of Bacillus acidicola , Bacillus pervagus and members of the genera Heyndrickxia , Margalitia and Weizmannia were evaluated. The 16S rRNA gene sequence similarity between Bacillus acidicola DSM 14745 T , Bacillus pervagus DSM 23947 T and members of the genera Heyndrickxia and Margalitia were above the cut-off level (>95 %) for genus delineation. Amino acid identity (AAI) values and the results of phylogenomic analysis suggested that B. acidicola and the members of the genera Heyndrickxia , Margalitia and Weizmannia belong to the same genus. Furthermore, the AAI and phylogenomic results also differentiate B. pervagus from B. acidicola and the members of the genera Heyndrickxia , Margalitia and Weizmannia . Based on the results, we propose to transfer Bacillus acidicola , Margalitia and Weizmannia to the genus Heyndrickxia . We also propose the reclassification of B. pervagus into a new genus Oikeobacillus gen. nov., with the type species Oikeobacillus pervagus comb. nov.
