A Gram-stain negative, non-flagellated, non-gliding and rod-shaped bacterium, strain JHH-2(T), was isolated from seawater collected in Jeju Island, Korea. The novel isolate was found to grow at 25-30 °C, at pH 6.5-7.0 and in the presence of 1-2% (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain JHH-2(T) is closely related to Siansivirga zeaxanthinifaciens JCM 17682(T), with 16S rRNA gene sequence similarity of 96.6%. The predominant respiratory quinone was identified as menaquinone-6 and the major cellular fatty acids were detected as iso-C(15:0), C(16:0) and iso-C(17:0) 3-OH. Polar lipid profiling revealed the presence of phosphatidylethanolamine, an unidentified glycolipid, four unidentified aminolipids and two unidentified lipids. The DNA G+C content of the chromosomal DNA of the type strain is 35.6 mol%. On the basis of several distinct phenotypic characteristics and phylogenetic analysis, a new species of the genus Siansivirga, Siansivirga jejuensis [corrected] JHH-2(T) sp. nov. is proposed. The type strain is JHH-2(T) (= KCCM 90230(T) = JCM 19228(T)). [corrected].
