abstract= A Gram-staining-negative, facultatively aerobic bacterium, strain XCD-X85T, was isolated from Xiaochaidan Lake, a salt lake (salinity 9.9  %, w/v) in Qaidam basin, Qinghai province, China. Its taxonomic position was determined by using a polyphasic approach. Cells of strain XCD-X85T were non-endospore-forming rods, 0.4–0.6 μm wide and 1.0–1.6 μm long, and motile by means of a single polar flagellum. Strain XCD-X85T was catalase- and oxidase-positive. Growth was observed in the presence of 0–12.0  % (w/v) NaCl (optimum, 1.0–2.0  %) and at 4–35 °C (optimum, 25–30 °C) and pH 6.5–10.5 (optimum, pH 8.0–8.5). Strain XCD-X85T contained (>10  %) summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c), C12 : 0, C16 : 0 and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) as the predominant fatty acids. The major respiratory quinone was ubiquinone 9 (Q-9). The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol. The DNA G+C content was 57.4 mol%. Phylogenetic trees based on 16S rRNA gene sequences showed that strain XCD-X85T was associated with the genus Pseudomonas, and showed highest 16S rRNA gene sequence similarities to Pseudomonas pelagia CL-AP6T (99.0  %) and Pseudomonas bauzanensis BZ93T (96.8  %). DNA–DNA relatedness of strain XCD-X85T to P. pelagia JCM 15562T was 19 ± 1  %. On the basis of the data presented above, it is concluded that strain XCD-X85T represents a novel species of the genus Pseudomonas, for which the name Pseudomonas salina sp. nov. is proposed. The type strain is XCD-X85T ( = CGMCC 1.12482T = JCM 19469T).,
