Abstract:
A Gram-stain-negative, aerobic, non-spore-forming, non-flagellated, non-gliding and rod-shaped bacterial strain, SSK2-2 T , was isolated from the place where the ocean and a freshwater spring meet at Jeju island, South Korea. Strain SSK2-2 T grew optimally at 30 °C, at pH 7.0–8.0 and in the presence of 2.0–3.0 % (w/v) NaCl. The neighbour-joining phylogenetic tree based on 16S rRNA gene sequences revealed that strain SSK2-2 T fell within the clade comprising the type strains of species of the genus Maribacter , joining the type strain of Maribacter sedimenticola with which it shared 99.4 % similarity. Sequence similarities to the type strains of other Maribacter species were 94.6–98.2 %. Strain SSK2-2 T contained MK-6 as the predominant menaquinone and iso-C 17 : 0 3-OH, iso-C 15 : 0 , iso-C 15 : 1 G, summed feature 3 (C 16 : 1 ω7 c and/or C 16 : 1 ω6 c ) and summed feature 9 (iso-C 17 : 1 ω9 c and/or 10-methyl C 16 : 0 ) as the major fatty acids. The major polar lipids of strain SSK2-2 T were phosphatidylethanolamine and one unidentified lipid. The DNA G+C content of strain SSK2-2 T was 38.2 mol% and mean levels of DNA–DNA relatedness with the type strains of four phylogenetically related species of the genus Maribacter were 11–24 %. Differential phenotypic properties, together with phylogenetic and genetic distinctiveness, revealed that strain SSK2-2 T is separate from other Maribacter species. On the basis of the data presented, strain SSK2-2 T is considered to represent a novel species of the genus Maribacter , for which the name Maribacter confluentis sp. nov. is proposed. The type strain is SSK2-2 T ( = KCTC 42604 T = CECT 8869 T ).
