title: Erythrobacter gangjinensis sp. nov., a marine bacterium isolated from seawater.
abstract: A novel Gram-negative, aerobic, orange-pigmented bacterial strain, designated K7-2(T), was isolated from seawater of Gangjin Bay, Korea, and subjected to a polyphasic taxonomic study. Strain K7-2(T) contained ubiquinone-10 (Q-10) as the predominant respiratory lipoquinone and did not produce bacteriochlorophyll a. Major fatty acids were C(18 : 1)omega7c (51.4 %), iso-C(15 : 0) 2-OH and/or C(16 : 1)omega7c (15.0 %) and C(17 : 1)omega6c (8.8 %). Major polar lipids were phosphatidylethanolamine and phosphatidylcholine. The DNA G+C content was 61.6 mol%. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain K7-2(T) formed a distinct phylogenetic lineage within the cluster comprising Erythrobacter strains. Similarities between the 16S rRNA gene sequences of strain K7-2(T) and the type strains of Erythrobacter species ranged from 95.0 % (Erythrobacter litoralis DSM 8509(T)) to 96.8 % (Erythrobacter citreus RE35F/1(T)). On the basis of polyphasic taxonomic data, strain K7-2(T) (=KCTC 22330(T)=JCM 15420(T)) is classified in a novel species within the genus Erythrobacter, for which the name Erythrobacter gangjinensis sp. nov. is proposed.
