Strain SSK2-1T grew optimally at 30 °C, at pH 7.0–8.0 and in the presence of 2.0 % (w/v) NaCl. Neighbour-joining, maximum-likelihood and maximum-parsimony phylogenetic trees based on 16S rRNA gene sequences revealed that strain SSK2-1T clustered with the type strains of two Octadecabacter species, showing 96.5–96.8 % 16S rRNA gene sequence similarity. Strain SSK2-1T and Octadecabacter arcticus DSM 13978T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c as the common major fatty acid. The polar lipid profile of strain SSK2-1T was similar to that of O. arcticus DSM 13978T by having phosphatidylcholine, phosphatidylglycerol and one unidentified aminolipid as the major components. The DNA G+C content of strain SSK2-1T was 60.1 mol%. Differential phenotypic properties, particularly temperature range for growth, oxidase activity and nitrate reduction, together with phylogenetic distinctiveness, revealed that strain SSK2-1T is separate from recognized species of the genus Octadecabacter . On the basis of the data presented, strain SSK2-1T is considered to represent a novel species of the genus Octadecabacter , for which the name Octadecabacter jejudonensis sp. nov. is proposed. The type strain is SSK2-1T ( = KCTC 32535T = CECT 8397T).", }
