Bacillus cibi sp. nov., isolated from jeotgal, a traditional Korean fermented seafood.
A Gram-variable, motile, endospore-forming, halotolerant bacillus, strain JG-30(T), was isolated from the traditional Korean fermented seafood jeotgal, and was subjected to a polyphasic taxonomic study. This organism grew optimally at 37 degrees C and in the presence of 0-1 % (w/v) NaCl. 16S rRNA gene sequence analysis showed that strain JG-30(T) forms a distinct phylogenetic lineage within the evolutionary radiation encompassed by the genus Bacillus. Strain JG-30(T) was characterized chemotaxonomically as having cell-wall peptidoglycan based on meso-diaminopimelic acid, MK-7 as the predominant menaquinone and iso-C(15 : 0) and iso-C(14 : 0) as the major fatty acids. The DNA G+C content was 45 mol%. Strain JG-30(T) exhibited levels of 16S rRNA gene sequence similarity of less than 95.7 % to Bacillus species with validly published names. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain JG-30(T) (=KCTC 3880(T)=DSM 16189(T)) was classified within the genus Bacillus as a novel species, for which the name Bacillus cibi sp. nov. is proposed.
