Alteromonas indica IO390401 was compared with Salinimonas sediminis N102 to examine the taxonomic relationship between the two type strains. The 16S rRNA gene sequence of A. indica IO390401 shared high similarity (99.9 %) with that of S. sediminis N102. The results of phylogenetic analyses based on 16S rRNA gene sequences indicated that the two strains formed a tight cluster within the genus Salinimonas. Whole genomic comparison between the two strains revealed an average nucleotide identity of 99.2 % and a digital DNA-DNA hybridization estimate of 92.6 %, strongly indicating that the two strains represented a single species. In addition, neither strain displayed any striking difference in metabolic, physiological or chemotaxonomic features. Therefore, we propose Alteromonas indica as a later heterotypic synonym of Salinimonas sediminis.
将印度交替单胞菌IO390401与沉积物盐单胞菌N102进行比较，以研究这两个模式菌株之间的分类关系。印度交替单胞菌IO390401的16S rRNA基因序列与沉积物盐单胞菌N102的序列具有高度相似性（99.9%）。基于16S rRNA基因序列的系统发育分析结果表明，这两个菌株在盐单胞菌属内形成了一个紧密的聚类。两个菌株之间的全基因组比较显示，平均核苷酸同一性为99.2%，数字DNA-DNA杂交估计值为92.6%，强烈表明这两个菌株代表同一个物种。此外，两个菌株在代谢、生理或化学分类特征上均未表现出任何显著差异。因此，我们提议将印度交替单胞菌作为沉积物盐单胞菌的晚出异名。
