A Gram-negative, rod-shaped, non-spore-forming, strictly aerobic strain with gliding motility, designated JAMB N27(T), was isolated from sediment adjacent to sperm whale carcasses off Kagoshima, Japan, at a depth of 219 m. Strain JAMB N27(T) contained MK-6 as the major isoprenoid quinone and iso-C₁₅:₀, iso-C₁₅:₁, C₁₆:₁ and iso-C₁₇:₁ as the predominant fatty acids. Casein, chitin, gelatin and starch were degraded. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain JAMB N27(T) represented a separate lineage within the genus Aquimarina. The DNA G+C content of strain JAMB N27(T) was 33.1 mol%. DNA-DNA relatedness values between strain JAMB N27(T) and type strains of species of the genus Aquimarina were significantly lower than the cut-off value accepted for the definition of a novel species. Therefore, strain JAMB N27(T) represents a novel species, for which the name Aquimarina macrocephali sp. nov. is proposed. The type strain is JAMB N27(T) (=JCM 15542(T)=NCIMB 14508(T)).
一株革兰氏阴性、杆状、不产芽孢、严格需氧、具有滑行运动能力的菌株，被命名为 JAMB N27(T)，是从日本鹿儿岛附近的抹香鲸尸体附近的沉积物中分离得到的，深度为 219 米。菌株 JAMB N27(T) 含有 MK-6 作为主要的类异戊二烯醌，iso-C₁₅:₀、iso-C₁₅:₁、C₁₆:₁ 和 iso-C₁₇:₁ 作为主要的脂肪酸。它能够降解酪蛋白、几丁质、明胶和淀粉。基于 16S rRNA 基因序列的系统发育分析表明，菌株 JAMB N27(T) 代表了 Aquimarina 属内的一个单独谱系。菌株 JAMB N27(T) 的 DNA G+C 含量为 33.1 mol%。菌株 JAMB N27(T) 与 Aquimarina 属种的模式菌株之间的 DNA-DNA 同源性值明显低于定义新种所接受的界限值。因此，菌株 JAMB N27(T) 代表了一个新的种，建议将其命名为 Aquimarina macrocephali sp. nov. 其模式菌株为 JAMB N27(T) (=JCM 15542(T)=NCIMB 14508(T))。
