title: Oceanobacillus bengalensis sp. nov., a bacterium isolated from seawater of the Bay of Bengal.
abstract: A Gram-stain positive, motile, and subterminal endospore-forming rod-shaped bacterium, designated strain Ma-21(T), was isolated from seawater of the Bay of Bengal. Strain Ma-21(T) was found to grow optimally at 37 °C and pH 8.0 with 3% (w/v) NaCl. Phylogenetic analyses showed that strain Ma-21(T) forms a distinct phylogenetic lineage close to Oceanobacillus chungangensis CAU 1051(T), Oceanobacillus caeni S-11(T), Oceanobacillus arenosus CAU 1183(T), Oceanobacillus halophilum GD01(T) and Ornithinibacillus heyuanensis GIESS003(T) in the family Bacillaceae. The cell wall of strain Ma-21(T) was found to contain meso-diaminopimelic acid as the diagnostic diamino acid, which is in line with those of members of the genus Oceanobacillus. The genomic DNA G+C content was determined to be 35.9 mol%. The only respiratory quinone detected was MK-7. The major cellular fatty acids were identified as anteiso-C(15:0) and anteiso-C(17:0). The major polar lipids were found to be diphosphatidylglycerol and phosphatidylglycerol. On the basis of phylogenetic, chemotaxonomic and phenotypic properties, strain Ma-21(T) is suggested to represent a novel species in the genus Oceanobacillus, for which the name Oceanobacillus bengalensis sp. nov. is proposed. The type strain is Ma-21(T) (=CGMCC 1.12799(T) = KCTC 33416(T) = MCCC 1K00260(T)).
