A halophilic archaeal strain, designated ZS-35-S2(T), was isolated from Zhoushan marine solar saltern in Zhejiang Province, China. Cells were pleomorphic, Gram-stain-negative and formed red-pigmented colonies on agar plates. The cells lysed in distilled water and the minimal NaCl concentration to prevent cell lysis was 8 % (w/v). Strain ZS-35-S2(T) was able to grow at 25-50 degrees C (optimum, 37 degrees C), with 1.4-4.8 M NaCl (optimum, 2.1 M), with 0-1.0 M MgCl2 (optimum, 0.1 M) and at pH 5.0-9.5 (optimum, pH 7.5). Phylogenetic tree reconstructions based on 16S rRNA genes and rpoB' genes revealed that strain ZS-35-S2(T) was distinct from the related genera Halomarina, Natronomonas, Halorientalis, Salinirubrum and Halobaculum of the order Halobacteriales. The major polar lipids of the strain were phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester and three unidentified glycolipids. The two major glycolipids were chromatographically identical to S-DGD-1 and DGD-1, respectively. The DNA G+C content of strain ZS-35-S2(T) is 67.0mol%. The phenotypic, chemotaxonomic and phylogenetic properties suggested that strain ZS-35-S2(T) (=CGMCC 1.12551(T)=JCM 30036(T)) represents a novel species of a new genus within the order Halobacteriales, for which the name Salinirubellus salinus gen. nov., sp. nov. is proposed.
