Presentation of Novel Strains of Halophile Bacteria Salinivibrio sp. from Urmia Lake

In this research، for the first time identification of moderate halophile microorganism of the genus Salinivibrio was studied، which leaded to identification of novel strains of this genus. Urmia Lake is a hypersaline lake located at the north-west region of Iran and it is the saltiest perennial lake of Iran and one of the rare perennial hyper saturation lakes in the world. At first، samples were collected from different sites of Urmia Lake and transferred to the laboratory under sterile conditions. After enrichment and culture of samples under defined conditions، repeated cultures were carried out to achieve pure cultures. Then selected strains were studied regarding phenotypic and phylogenetic (by sequencing 16S rRNA technique) characteristics. From total strains which were belonged to Salinivibrio sp.، 57% and 43% of the strains showed closest similarity with S. costicola subsp. alcaliphilus and S. sharmensis، respectively. This study is attempted to present of novel genetic pools from great microbial sources of Urmia Lake and especially Salinivibrio sp. that they are the base of wide applications in biotechnological science.
