      Abstract: Strain Con a/3T is a Gram-positive, motile, endospore-
      forming, rod-shaped and arsenic-resistant bacterium, which was
      isolated from a concretion of arsenic ore obtained from a bore-hole.
      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(7cis) 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).
