title: Erythrobacter westpacificensis sp. nov., a marine bacterium isolated from the Western Pacific.
abstract: A novel Gram-negative, orange-pigmented bacterial strain JLT2008(T) was isolated from the surface seawater of the Western Pacific and subjected to a polyphasic taxonomic study. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain JLT2008(T) belonged to the genus Erythrobacter, sharing the highest similarity (96.6 %) with Erythrobacter gangjinensis K7-2(T) and the lowest similarity (94.9 %) with Erythrobacter litoralis DSM 8509(T). Strain JLT2008(T) did not contain bacteriochlorophyll a, and the predominant respiratory lipoquinone was ubiquinone-10. The major fatty acids were C(18:1) ω7c, C(16:0), C(16:1) ω7c/C(16:1) ω6c. The prominent polar lipids were sphingoglycolipid, phosphatidylethanolamine, and phosphatidylglycerol. The genomic G + C content was 60.1 mol %. Based on the polyphasic taxonomic data, a novel species within the genus Erythrobacter, and with the name Erythrobacter westpacificensis sp. nov., is proposed. The type strain is JLT2008(T) (=CGMCC 1.10993(T) = JCM 18014(T)).
