A slightly halophilic alphaproteobacterium, designated CL-SP26T, was isolated from hypersaline water of a solar saltern located in Seosin, Korea. 16S rRNA gene sequence analysis revealed an affiliation with the genus Jannaschia. Sequence similarities between CL-SP26T and type strains of members of the genus Jannaschia were 94.9-97.2%. Cells were rod-shaped and motile with one or more monopolar flagella. Strain CL-SP26T grew on solid media as circular red colonies. It was able to grow in 3-10% sea salt; however, no growth occurred in media containing NaCl as the only salt. Strain CL-SP26T grew at 5-35 °C and pH 7-10. The major fatty acids were 18:1ω7c (64%) and 18:0 (12.0%). Three fatty acids, 3-OH 14:0/iso 16:1 (3.6%), 18:3ω6c (2.2%) and 10-methyl 19:0 (1.9%), found in minor quantities in CL-SP26T are unique among Jannaschia species. The DNA G + C content was 63 mol%. According to physiological data, fatty acid composition and 16S rRNA gene sequence analysis, CL-SP26T was assigned to the genus Jannaschia, but could be distinguished from recognized species of the genus. Strain CL-SP26T (= KCCM 42114T = JCM 13035T) therefore represents a novel species, for which the name Jannaschia seosinensis sp. nov. is proposed.
