Int J Syst Evol Microbiol. 2013 Apr;63(Pt 4):1421-1426. doi: 10.1099/ijs.0.038349-0. Epub 2012 Jul 27.


A Gram-staining-negative, yellow-pigmented, non-motile, strictly aerobic, rod-shaped bacterium, designated strain CNU001(T), was isolated from seawater collected on the coast of Jeju Island, South Korea, and subjected to a polyphasic taxonomic study. The temperature, pH and NaCl ranges for growth were 10-30 °C, pH 6.0-10.0 and 2.0-5.0 %, respectively. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain CNU001(T) belonged to the genus Erythrobacter in the family Erythrobacteraceae, with Erythrobacter longus DSM 6997(T) (96.6 % sequence similarity), Erythrobacter gaetbuli SW-161(T) (96.3 %), Erythrobacter vulgaris 022 2-10(T) (96.2 %), Erythrobacter nanhaisediminis T30(T) (96.1 %) and other members of the genus Erythrobacter (<96.0 %) identified as the novel strain's closest relatives. The major cellular fatty acids were C18 : 1ω7c and C17 : 1ω6c. The polar lipids were found to be diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, phosphatidylglycerol, one sphingoglycolipid, one unidentified aminolipid and six other unidentified lipids. The major respiratory quinone was ubiquinone-10 (UQ-10) and the genomic DNA G+C content of the novel strain was 58.9 mol%. On the basis of phenotypic, phylogenetic and genotypic data, strain CNU001(T) represents a novel species within the genus Erythrobacter, for which the name Erythrobacter jejuensis sp. nov. is proposed. The type strain is CNU001(T) ( = KCTC 23090(T) = JCM 16677(T)).
