abstract= A Gram-negative, coccoid to rod-shaped, strictly aerobic bacterium, strain CL-GR66T, was isolated from coastal seawater collected off Korea. The strain grew optimally in the presence of 3–5 % sea salts, at a temperature of 30 °C and at pH 7. The polar lipid profile of strain CL-GR66T comprised phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, two unidentified aminolipids, an unidentified glycolipid and an unidentified lipid. The major fatty acids were C18 : 1 ω7c (71.4 %), 11-methyl C18 : 1 ω7c (11.3 %), C16 : 0 (6.4 %), C18 : 0 (4.6 %) and C12 : 1 3-OH (3.0 %). Ubiquinone 10 was the major quinone. The DNA G+C content was 67.9 mol%. 16S rRNA gene sequence analysis revealed that strain CL-GR66T belonged to the Roseobacter clade within the family Rhodobacteraceae. Strain CL-GR66T was related most closely to the type strain of Marinovum algicola (95.5 % 16S rRNA gene sequence similarity), and sequence similarities between strain CL-GR66T and other type species of the Roseobacter clade ranged from 91.8 to 95.4 %. Phylogenetic analyses of 16S rRNA gene sequences showed that strain CL-GR66T was not associated with any known genus in the family Rhodobacteraceae. The distinct phylogenetic position of strain CL-GR66T, its phylogenetic distance from genera of the family Rhodobacteraceae, together with phenotypic data, suggest that the organism represents a novel species of a new genus, for which the name Ponticoccus litoralis gen. nov., sp. nov. is proposed. The type strain of Ponticoccus litoralis is CL-GR66T (=KCCM 90028T =DSM 18986T).,
