A Gram-staining-negative, aerobic, non-spore-forming, non-flagellated, non-gliding and rod-shaped bacterial strain, SSK3-3T, was isolated from the zone where the ocean and a freshwater spring meet at Jeju island, South Korea. Strain SSK3-3T grew optimally at 30 °C, at pH 7.0–8.0 and in the presence of 2.0 % (w/v) NaCl. Phylogenetic trees based on 16S rRNA gene sequences revealed that strain SSK3-3T clustered with the type strains of species of the genus Kordia , with which it exhibited 96.5–97.2 % 16S rRNA gene sequence similarity. Sequence similarities to the type strains of other recognized species were less than 92.2 %. Strain SSK3-3T contained MK-6 as the predominant menaquinone and iso-C15 : 0, iso-C17 : 0 3-OH, iso-C15 : 0 3-OH and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) as the major fatty acids. The major polar lipids of strain SSK3-3T were phosphatidylethanolamine, one unidentified lipid and one unidentified glycolipid. The DNA G+C content of strain SSK3-3T was 34.9 mol% and the mean DNA–DNA relatedness with Kordia periserrulae KACC 14311T was 12 %. The differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, revealed that strain SSK3-3T is separate from other species of the genus Kordia . On the basis of the data presented, strain SSK3-3T is considered to represent a novel species of the genus Kordia , for which the name Kordia jejudonensis sp. nov. is proposed. The type strain is SSK3-3T ( = KCTC 32426T = CECT 8368T). An emended description of the genus Kordia is also provided.

The predominant cellular fatty acids were summed feature 3 (comprising iso-C15 : 0 2-OH and/or C16 : 1ω7c, 41.5 %), iso-C15 : 0 (26.7 %) and C16 : 0 (9.6 %), and menaquinone MK-7 was the only respiratory quinone. The G+C content of the genomic DNA of strain No.6T was 36.8 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain No.6T fell within the evolutionary group encompassed by the genus Sphingobacterium . Levels of 16S rRNA gene sequence similarity between the novel strain and the type strains of recognized Sphingobacterium species ranged from 92.1 to 99.1 %, the highest values being with Sphingobacterium siyangense SY1T (99.1 %) and Sphingobacterium multivorum IAM 14316T (98.5 %). DNA–DNA relatedness between strain No.6T and these two type strains were 32.0 and 5.7 %, respectively. The polar lipids found in strain No.6T were phosphatidylethanolamine, two unidentified phospholipids, three unidentified aminophospholipids, one glycolipid and four unidentified lipids. One unidentified sphingolipid was also found. On the basis of phenotypic and genotypic data, strain No.6T represents a novel species of the genus Sphingobacterium , for which the name Sphingobacterium cladoniae sp. nov. is proposed. The type strain is No.6T ( = KCTC 22613T = JCM 16113T). An emended description of Sphingobacterium siyangense is also proposed.
