A Gram-negative marine bacterium, designated strain En6(T), was isolated from seawater of the East Sea of Korea. The organism grew in 1-25 % (w/v) NaCl and at 10-37 degrees C and pH 5.3-9.3, with optimal growth occurring in 4-5 % NaCl and at 25-30 degrees C and pH 7.5. Phylogenetic analysis of the 16S rRNA gene sequence of strain En6(T) placed this bacterium in the clade Marinobacter within the class Gammaproteobacteria. The 16S rRNA gene sequence similarity between strain En6(T) and Marinobacter lipolyticus SM19(T), the most closely related species, was 98.4 %, and the level of DNA-DNA relatedness between the two strains was 22 %. On the basis of the phylogenetic analysis and phenotypic and chemotaxonomic data, strain En6(T) is considered to represent a novel species of the genus Marinobacter. The name Marinobacter goseongensis sp. nov. is proposed, with strain En6(T) (=KCTC 12515(T)=DSM 19471(T)) as the type strain.
从韩国东海海水中分离出一株革兰氏阴性海洋细菌，命名为En6(T)菌株。该菌株能在1%-25%（w/v）NaCl、10-37℃和pH 5.3-9.3条件下生长，最适生长条件为4%-5% NaCl、25-30℃和pH 7.5。对En6(T)菌株16S rRNA基因序列进行系统发育分析，结果表明该菌属于γ-变形菌纲海杆菌属分支。En6(T)菌株与最相近的解脂海杆菌SM19(T)菌株的16S rRNA基因序列相似性为98.4%，两菌株间的DNA-DNA杂交率为22%。基于系统发育分析、表型特征和化学分类学数据，En6(T)菌株被认为代表海杆菌属的一个新物种。建议将其命名为固城海杆菌（Marinobacter goseongensis sp. nov.），模式菌株为En6(T)菌株（=KCTC 12515(T)=DSM 19471(T)）。
