A Gram-positive-staining, rod-shaped, motile, spore-forming and moderately halotolerant bacterium, designated ZLC-26T, was isolated from a sand soil sample collected from Xinjiang Province, China, and was characterized by using a polyphasic taxonomic approach. This isolate grew optimally at 30–37 °C and pH 7–8. It grew with 0–8% NaCl (optimum, 0–2 %). Comparative 16S rRNA gene sequence analysis showed that strain ZLC-26T was closely related to members of the genus Bacillus, exhibiting the highest 16S rRNA gene sequence similarities to Bacillus nealsonii DSM 15077T (97.1 %), B. shackletonii LMG 18435T (97.0 %), B. siralis 171544T (97.0 %), B. circulans IAM 12462T (96.7 %) and B. pocheonensis Gsoil 420T (96.7 %). Strain ZLC-26T contained MK-7 as the predominant menaquinone. The diagnostic diamino acid in the cell-wall peptidoglycan was meso-diaminopimelic acid. The major cellular fatty acids were iso-C15 : 0, C16 : 1 ω11c and anteiso-C15 : 0. The DNA G+C content was 38.2 mol%. These chemotaxonomic results supported the affiliation of strain ZLC-26T to the genus Bacillus. However, low DNA–DNA relatedness values and distinguishing phenotypic characteristics allowed genotypic and phenotypic differentiation of strain ZLC-26T from recognized Bacillus species. On the basis of the evidence presented, strain ZLC-26T is considered to represent a novel species of the genus Bacillus, for which the name Bacillus korlensis sp. nov. is proposed. The type strain is ZLC-26T (=CCTCC AB 207172T=NRRL B-51302T).
