A rod-shaped, Gram-staining-negative and orange-pigmented bacterium, designated strain HME9302, was isolated from seawater of the Yellow Sea in the Republic of Korea. The phylogenetic tree based on 16S rRNA gene sequences showed that strain HME9302 formed a lineage within the genus Altererythrobacter, and was most closely related to Altererythrobacter aurantiacus O30 with 96.7 % sequence similarity. The major fatty acids were summed feature 8 (comprising C18 : 1ω7c and/or C18 : 1ω6c), summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c) and C16 : 0. The major respiratory quinone was ubiquinone-10. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, sphingoglycolipid and four unidentified lipids. The DNA G+C content was 60.8 mol%. On the basis of the evidence presented in this study, strain HME9302 represents a novel species of the genus Altererythrobacter, for which the name Altererythrobacter maritimus sp. nov. is proposed with the type strain HME9302 (=KCTC 32463=KACC 17617=CECT 8417).
从大韩民国黄海海水中分离出一株杆状、革兰氏染色阴性且产橙色色素的细菌，命名为HME9302菌株。基于16S rRNA基因序列构建的系统发育树表明，HME9302菌株在交替赤杆菌属内形成一个分支，与橙色交替赤杆菌O30的亲缘关系最近，序列相似性为96.7%。主要脂肪酸为总和特征8（包含C18:1ω7c和/或C18:1ω6c）、总和特征3（包含C16:1ω7c和/或C16:1ω6c）和C16:0。主要呼吸醌为泛醌-10。主要极性脂为双磷脂酰甘油、磷脂酰甘油、磷脂酰乙醇胺、磷脂酰胆碱、鞘糖脂和四种未鉴定的脂类。DNA G+C含量为60.8 mol%。基于本研究提供的证据，HME9302菌株代表交替赤杆菌属的一个新物种，为此提出名为海洋交替赤杆菌（Altererythrobacter maritimus）的新物种，模式菌株为HME9302（=KCTC 32463=KACC 17617=CECT 8417）。
