The bacterium grew in the presence of 20 mM arsenate and 0·5 mM arsenite. Diaminopimelic acid was present in the cell wall peptidoglycan, MK-7 was the major menaquinone, and iso-C15 : 0, anteiso-C15 : 0, iso-C16 : 0 and C16 : 1(δ7cis) were the major fatty acids. Based on its phenotypic, chemotaxonomic and phylogenetic characteristics, strain Con a/3T was identified as a member of the genus Bacillus. It exhibited maximum similarity (97 %) at the 16S rRNA gene level with Bacillus barbaricus (DSM 14730T); however, the DNA–DNA relatedness value with B. barbaricus was 60 %. Strain Con a/3T also exhibited a number of phenotypic differences from B. barbaricus (DSM 14730T). Strain Con a/3T was therefore identified as representing a novel species of the genus Bacillus, for which the name Bacillus arsenicus sp. nov. is proposed. The type strain is Con a/3T (=MTCC 4380T=DSM 15822T=JCM 12167T).", }
