Five strains of halophilic, Gram-negative marine bacteria (KMM 3809(T), KMM 3814, KMM 3815, KMM 3817 and KMM 3818) were isolated from sediments collected from Chazhma Bay, Sea of Japan. Phylogenetic 16S rRNA gene sequence-based analysis placed these bacteria in a clade within the genus Marinobacter in the gamma-Proteobacteria. KMM 3809(T) showed highest 16S rRNA gene sequence similarity of 97.3 % to Marinobacter litoralis and 96.9 % to Marinobacter hydrocarbonoclasticus and Marinobacter aquaeolei. DNA-DNA hybridization between the five isolates was at the conspecific level (94-96 %) and that among the closest phylogenetic neighbours ranged from 45.0 to 62.5 %. The new organisms were susceptible to polymyxin. Predominant fatty acids were C(16 : 0), C(16 : 1)omega9c, C(16 : 1)omega7c and C(18 : 1)omega9c. Phylogenetic evidence, along with phenotypic and genotypic characteristics, showed that the bacteria constituted a novel species of the genus Marinobacter. The name Marinobacter excellens sp. nov. is proposed for this species, with the type strain KMM 3809(T) (=CIP 107686(T)).
从日本海茶谷湾采集的沉积物中分离出五株嗜盐革兰氏阴性海洋细菌（KMM 3809(T)、KMM 3814、KMM 3815、KMM 3817和KMM 3818）。基于系统发育16S rRNA基因序列的分析将这些细菌置于γ-变形菌纲海杆菌属内的一个进化枝中。KMM 3809(T)与滨海海杆菌的16S rRNA基因序列相似性最高，为97.3%，与破环烃海杆菌和水生海杆菌的相似性为96.9%。五株分离株之间的DNA-DNA杂交处于同种水平（94-96%），与最接近的系统发育邻株之间的杂交率为45.0%至62.5%。这些新生物对多粘菌素敏感。主要脂肪酸为C(16 : 0)、C(16 : 1)ω9c、C(16 : 1)ω7c和C(18 : 1)ω9c。系统发育证据以及表型和基因型特征表明，这些细菌构成了海杆菌属的一个新物种。为此物种提议命名为卓越海杆菌（Marinobacter excellens sp. nov.），模式菌株为KMM 3809(T)（=CIP 107686(T)）。
