In order to investigate the taxonomic status and potential of model organism for salinity adaptation, the bacterial strain DYB, a euryhaline bacterium, was characterized on the basis of its morphological, physiological, and biochemical analyses. For further determining its phylogenetic position, the 16S rRNA gene of DYB was sequenced and compared with that of the correlative strains, molecular phylogenetic dendrogram was constructed based on genetic distance analysis. Results showed that bacterial strain DYB exhibited the highest levels of similarity to the Idiomarina sp. H-76 (KF021759). Based on these results, the bacterial strain DYB was identified as Idiomarina sp. DYB. In addition, bacterial strain DYB has potential advantages to be a model organism for investigating salinity adaptation because of its euryhalinity, biochemical and physiological characteristics as well as adaptation strategies.
