A slightly halophilic alphaproteobacterium, designated CL-SP26, was isolated from hypersaline water of a solar saltern located in Seosin, Korea. 16S rRNA gene sequence analysis revealed an affiliation with the genus . Sequence similarities between CL-SP26 and type strains of members of the genus were 94·9–97·2 %. Cells were rod-shaped and motile with one or more monopolar flagella. Strain CL-SP26 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-SP26 grew at 5–35 °C and pH 7–10. The major fatty acids were 18 : 17 (64 %) and 18 : 0 (12·0 %). Three fatty acids, 3-OH 14 : 0/iso 16 : 1 (3·6 %), 18 : 36 (2·2 %) and 10-methyl 19 : 0 (1·9 %), found in minor quantities in CL-SP26, are unique among species. The DNA G+C content was 63 mol%. According to physiological data, fatty acid composition and 16S rRNA gene sequence analysis, CL-SP26 was assigned to the genus , but could be distinguished from recognized species of the genus. Strain CL-SP26 (=KCCM 42114=JCM 13035) therefore represents a novel species, for which the name sp. nov. is proposed.
