A halotolerant, round-endospore-forming, aerobic, Gram-positive bacterium, designated BH724(T), was isolated from a solar saltern at Taean in Korea. Cells of this strain were rod-shaped and found to be non-motile. Strain BH724(T) grew at salinities of 0.10 % (w/v) NaCl with an optimum of 3 % (w/v) NaCl and at temperatures of 15-50 degrees C with an optimum of 40 degrees C. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain BH724(T) belonged to the genus Bacillus and that Bacillus aquimaris TF-12(T), Bacillus marisflavi TF-11(T) and Bacillus vietnamensis JCM 11124(T) were its closest neighbours, sharing 97.3, 97.2 and 97.0% 16S rRNA gene sequence similarity, respectively. The genomic DNA G + C content was 39 mol% and the predominant menaquinone was MK-7. Its major cellular fatty acids were anteiso-C-15:0, iso-C-15:0, iso-C-16: 0 and iso-C-14: 0. The peptidoglycan type was A1 alpha, linked directly through L-lysine. On the basis of morphological, chemotaxonomic, physiological and phylogenetic properties, strain BH724(T) represents a novel species of the genus Bacillus, for which the name Bacillus seohaeanensis sp. nov. is proposed. The type strain is BH724(T) (= KCTC 3913(T) = DSM 16464(T)).
