title: Erythrobacter lutimaris sp. nov., isolated from a tidal flat sediment.
abstract: A Gram-stain-negative, non-motile, coccoid- or oval-shaped bacterial strain, designated S-5(T), belonging to the class Alphaproteobacteria, was isolated from a tidal flat sediment of the Yellow Sea, Korea and was subjected to a polyphasic taxonomic study. Strain S-5(T) grew optimally at pH 7.0-8.0, at 30 °C and in the presence of 2-3 % (w/v) NaCl. Neighbour-joining analysis based on 16S rRNA gene sequences showed that strain S-5(T) fell within the clade comprising the species of the genus Erythrobacter, clustering with the type strains of Erythrobacter pelagi, Erythrobacter citreus and Erythrobacter seohaensis with which it exhibited the highest 16S rRNA gene sequence similarity (96.0-96.7 %). The DNA G+C content was 66.0 mol%. Strain S-5(T) contained Q-10 as the predominant ubiquinone and summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c) and C17 : 1ω6c as the major fatty acids. The major polar lipids were sphingoglycolipid, phosphatidylcholine, phosphatidylglycerol, an unidentified glycolipid and two unidentified lipids. Differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, demonstrated that strain S-5(T) is distinguishable from other species of the genus Erythrobacter. On the basis of the data presented, strain S-5(T) is considered to represent a novel species of the genus Erythrobacter, for which the name Erythrobacter lutimaris sp. nov. is proposed. The type strain is S-5(T) ( = KCTC 42109(T) = CECT 8624(T)).
