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)).
一株革兰氏阴性、黄色、非运动、严格需氧、杆状细菌，被命名为 CNU001(T)，从韩国济州岛海岸采集的海水中分离得到，并进行了多相分类学研究。该菌的最适生长温度、pH 值和 NaCl 范围分别为 10-30°C、pH 6.0-10.0 和 2.0-5.0%。基于 16S rRNA 基因序列的系统发育分析表明，菌株 CNU001(T)属于红杆菌属的红杆菌科，与长红杆菌 DSM 6997(T)（96.6%序列相似性）、盖氏红杆菌 SW-161(T)（96.3%）、普通红球菌 022 2-10(T)（96.2%）、南海水域红杆菌 T30(T)（96.1%）和其他红杆菌属的种（<96.0%）最为接近。主要的细胞脂肪酸为 C18:1ω7c 和 C17:1ω6c。极性脂类由二磷脂酰甘油、磷脂酰乙醇胺、磷脂酰胆碱、磷脂酰甘油、一个神经酰胺糖脂、一个未鉴定的氨基脂类和六个其他未鉴定的脂类组成。主要的呼吸醌为泛醌-10（UQ-10），新菌株的基因组 DNA G+C 含量为 58.9 mol%。根据表型、系统发育和基因型数据，菌株 CNU001(T)代表红杆菌属中的一个新种，命名为济州红杆菌（Erythrobacter jejuensis）sp. nov.。模式菌株为 CNU001(T)（=KCTC 23090(T)=JCM 16677(T)）。
