Abstract
- Three novel, Gram-stain-positive, obligate aerobic, catalase- and oxidase-positive bacterial strains, designated B2O-1(T), T2O-4(T), and 0.2-SM1T-5(T), were isolated from jeotgal, a traditional Korean fermented seafood. Strains B2O-1(T), T2O-4(T), and 0.2-SM1T-5(T) exhibited distinct colony colors, characterized by pink, yellow, and red opaque circular colonies, respectively. Phylogenetic analysis revealed that three strains formed a paraphyletic clade within the genus Sporosarcina and shared < 99.0% similarity with Sporosarcina aquimarina KCTC 3840(T) and Sporosarcina saromensis KCTC 13119(T) in their 16S rRNA gene sequences. The three strains exhibiting Orthologous Average Nucleotide Identity values < 79.3% and digital DNA-DNA hybridization values < 23.1% within the genus Sporosarcina affirmed their distinctiveness. Strains B2O-1(T), T2O-4(T), and 0.2-SM1T-5(T) contained MK-7 as a sole respiratory menaquinone and A4α type peptidoglycan based on lysine with alanine, glutamic acid, and aspartic acid. The common polar lipids include diphosphatidylglycerol, phosphatidylglycerol, and phosphatidylethanolamine. Strain T2O-4(T) contained one unidentified phospholipid, whereas strain 0.2-SM1T-5(T) contained two unidentified phospholipids. Cellular fatty acid profiles, with C(15:0) anteiso as the major fatty acid, supported the affiliation of the three strains to the genus Sporosarcina. Based on the polyphasic characteristics, strains B2O-1(T) (= KCTC 43506(T) = JCM 36032(T)), T2O-4(T) (= KCTC 43489(T) = JCM 36031(T)), and 0.2-SM1T-5(T) (= KCTC 43519(T) = JCM 36034(T)) represent three novel species within the genus Sporosarcina, named Sporosarcina jeotgali sp. nov., Sporosarcina oncorhynchi sp. nov., and Sporosarcina trichiuri sp. nov., respectively.

Abstract
- Strain B31T is a Gram-staining-negative, motile, and extremely halophilic archaeon that was isolated from salt-fermented seafood. Its morphology, physiology, biochemical features, and 16S rRNA gene sequence were determined. Phylogenetic analysis of its 16S rRNA gene sequence and composition of its major polar lipids placed this archaeon in the genus Halorubrum of the family Halobacteriaceae. Strain B31T showed 97.3, 97.2, and 96.9% 16S rRNA similarity to the type strains of Halorubrum alkaliphilum, Hrr. tibetense, and Hrr. vacuolatum, respectively. Its major polar lipids were phosphatidylglycerol (PG), phosphatidylglycerol phosphate methyl ester (PGP-Me) and sulfated diglycosyl diether (S-DGD). Genomic DNA from strain B31T has a 61.7 mol% G+C content. Analysis of 16S rRNA gene sequences, as well as physiological and biochemical tests, identified genotypic and phenotypic differences between strain B31T and other Halorubrum species. The type strain of the novel species is B31T (=JCM 15757T =DSM 19504T).
