An investigation into the taxonomic position of Bacillus isronensis MTCC 7902T revealed that the strain shares a common phylogenetic lineage with Solibacillus silvestris MTCC 10789T. It displays considerable overlap in phenotypic properties with the genus Solibacillus, including endospore shape and position, oxidase and catalase activities, presence of iso-C15 : 0, C16 : 1ω7c alcohol and iso-C17 : 1ω7c as major cellular fatty acids, A4α-type cell-wall peptidoglycan, polar lipids and menaquinone pattern. These features reinforce the findings of molecular phylogenetic analyses based on 16S rRNA gene, gyrB gene and 16S-23S internal transcribed spacer (ITS) region sequences and, in line with the recommendations of Kämpfer et al. [Int J Syst Evol Microbiol 56 (2006), 781-786], provide justification for the transfer of Bacillus isronensis from the genus Bacillus to Solibacillus as Solibacillus isronensis comb. nov. The type strain is B3W22T ( = MTCC 7902T = DSM 21046T = JCM 13838T). An emended description of the genus Solibacillus is also provided.
