菌株DSK 1是从日本海沟6,356 m深处分离的一种新的中度嗜压细菌。基于16 S核糖体DNA序列的系统发育分析表明，菌株DSK 1代表一个单独的谱系与希瓦氏菌barophiles分支，是密切相关的Moritella marina。对菌株DSK 1的生长温压范围和某些生化特性的比较表明，菌株DSK 1与M. marina和Shewanella barophilic物种。此外，菌株DSK 1显示出与Moritella和Shewanella型菌株低水平的DNA相似性;然而，该分离株特征性地产生DHA（22：6）作为膜脂肪酸，并且该菌株的脂肪酸谱与M.码头由于这些差异，DSK 1菌株似乎代表了一种新的深海Moritella物种。建议将其命名为Moritella japonica。模式菌株为JCM 10249。
Strain DSK1 is a novel moderately barophilic bacterium isolated from the Japan Trench at a depth of 6,356 m. Phylogenetic analysis based on 16S ribosomal DNA sequences showed that strain DSK1 represents a separate lineage with the Shewanella barophiles branch and is closely related to Moritella marina. Comparisons of the temperature and pressure range for growth and some biochemical characteristics indicate that strain DSK1 differs from M. marina and Shewanella barophilic species. Furthermore, strain DSK1 displays a low level of DNA similarity to the Moritella and Shewanella type strains; however this isolate characteristically produces DHA (22:6) as a membrane fatty acids, and the fatty acid profile of this strain is similar to that of M. marina. Because of these differences, strain DSK1 appears to represent a novel deep-sea Moritella species. The name Moritella japonica is proposed. The type strain is JCM 10249.
