Bacillus berkeleyi sp. nov., isolated from the sea urchin Strongylocentrotus intermedius.

???displayArticle.abstract???
A bacterial strain, designated KMM 6244(T), was isolated from the sea urchin Strongylocentrotus intermedius and subjected to a polyphasic taxonomic investigation. The bacterium was found to be heterotrophic, aerobic, non-motile and spore-forming. Comparative phylogenetic analysis based on 16S rRNA gene sequencing placed the marine isolate in the genus Bacillus. The nearest neighbor of strain KMM 6244(T) was Bacillus decolorationis LMG 19507(T) with a 16S rRNA gene sequence similarity of 98.0%. Sequence similarities with the other recognized Bacillus species were less than 96.0%. The results of the DNA-DNA hybridization experiments revealed a low relatedness (37%) of the novel isolate with the type strain of B. decolorationis LMG 19507(T). Strain KMM 6244(T) grew at 4-45°C and with 0-12% NaCl. It produced catalase and oxidase and hydrolyzed aesculin, casein, gelatin and DNA. The predominant fatty acids were anteiso-C(15:0), iso-C(15:0), anteiso-C(17:0), C(15:0), iso-C(16:0) and iso-C(14:0). The DNA G + C content was 39.4 mol%. A combination of phylogenetic, genotypic and phenotypic data clearly indicated that strain KMM 6244(T) represents a novel species in the genus Bacillus, for which the name Bacillus berkeleyi sp. nov. is proposed. The type strain is KMM 6244(T) (KCTC 12718(T) = LMG 26357(T)).
