A Gram-negative, non-motile, ovoid to rod-shaped bacterium, designated strain HWDM-33T, was isolated from seawater of the Yellow Sea, Korea, and was subjected to a polyphasic taxonomic study. Strain HWDM-33T grew optimally at pH 7–8, at 25 °C and in the presence of 2–3 % (w/v) NaCl. Neighbour-joining, maximum-likelihood and maximum-parsimony phylogenetic trees based on 16S rRNA gene sequences showed that strain HWDM-33T clustered with Erythrobacter gangjinensis K7-2T, with which it shared 96.9 % sequence similarity. Strain HWDM-33T exhibited 94.2–95.8 % 16S rRNA gene sequence similarity to the type strains of other recognized species of the genus Erythrobacter . Strain HWDM-33T contained Q-10 as the predominant ubiquinone and C18 : 1ω7c, C17 : 1ω6c, and C16 : 1ω7c and/or iso-C15 : 0 2-OH as the major fatty acids. The major polar lipids were sphingoglycolipid, phosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine and an unidentified lipid. The DNA G+C content of strain HWDM-33T was 66.1 mol%. Differential phenotypic properties and phylogenetic distinctiveness demonstrated that strain HWDM-33T was separate from E. gangjinensis and other recognized species of the genus Erythrobacter . On the basis of the data presented here, strain HWDM-33T represents a novel species of the genus Erythrobacter , for which the name Erythrobacter marinus sp. nov. is proposed. The type strain is HWDM-33T ( = KCTC 23554T  = CCUG 60528T).

Gram-negative strains, motile by a single polar flagellum, non-pigmented and with a curved rod-shaped morphology, designated IMCC1826T and IMCC1883, were isolated from a surface seawater sample from the Yellow Sea. The two strains shared 99.9 % 16S rRNA gene sequence similarity and showed 92 % DNA–DNA relatedness, suggesting that they belonged to the same genomic species. Phylogenetic analysis based on 16S rRNA gene sequences showed that the two isolates were related most closely to the type strain of Thalassolituus oleivorans with a sequence similarity of 96.4 % and formed a robust phyletic lineage with T. oleivorans . DNA–DNA relatedness between the two strains and T. oleivorans DSM 14913T was 8.7–11.6 %. A putative alkane hydroxylase (alkB) gene was detected in strain IMCC1826T by PCR, but the amino acid sequence of the gene was distantly related to that of the AlkB homologue of T. oleivorans DSM 14913T. As expected from the presence of the alkB gene, the new strains utilized n-tetradecane and n-hexadecane as a carbon source. The DNA G+C content was 54.6–56.0 mol% and the main isoprenoid quinone detected was Q-9. Polar lipids of strain IMCC1826T included diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and amino-group-containing lipids. On the basis of taxonomic data obtained in this study, strains IMCC1826T and IMCC1883 represent a novel species of the genus Thalassolituus , for which the name Thalassolituus marinus sp. nov. is proposed, with IMCC1826T ( = KCTC 23084T = NBRC 107590T) as the type strain.
