A bacterial strain, designated Npb-02T, was isolated from a freshwater river in Taiwan and characterized in a taxonomic study using a polyphasic approach. Cells of strain Npb-02T were Gram-stain-negative, aerobic, poly-β-hydroxybutyrate-accumulating, rod-shaped and non-motile. Growth occurred at 15–40 °C (optimum 25–30 °C), at pH 7.0–8.0 (optimum pH 7.0) and with 0–1 % NaCl (optimum 0.5 %). Phylogenetic analyses based on 16S rRNA gene sequences showed that strain Npb-02T belonged to the genus Vogesella and was most closely related to Vogesella perlucida DS-28T with sequence similarity of 98.3 %. Strain Npb-02T contained summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c) and C16 : 0 as the major fatty acids. The major respiratory quinone was Q-8.The polar lipid profile consisted of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, an uncharacterized aminophospholipid and an uncharacterized phospholipid. The genomic DNA G+C content of strain Npb-02T was 64.1 mol%.

Abstract Strain WN019T, an aerobic, motile, and pleomorphic rods bacterium, was isolated from the natural saline-alkali wetland soil of Binhai new district, Tianjin, China. Cells of strain WN019T were 0.5-0.8 µm in width and 2.0-2.5 µm in length, and the growth occurred optimally at 33-37 ℃, pH 7.5-8.0, and in the presence of 15.0-20.0 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that the isolate belonged to the genus Halorubrum and exhibited high sequence similarity of 97.8 % to Halorubrum saccharovorum JCM 8865T. The major respiratory quinone of strain WN019T were MK-8 and MK-8 (H2), and the major polar lipids were Glycolipid (GL), Phospholipid (PL), Phosphatidylglycerol-Sulfate (PGS), Phosphatidylglycerol (PG) and Phosphatidylglycerol-Phosphate-Methyl Ester (Me-PGP). The DNA G+C content of the strain was 67.3 mol%. The average nucleotide identity (ANI) based on whole genome sequences of strain WN019T and Halorubrum saccharovorum JCM 8865T was 87.5 %, and the digital DNA-DNA hybridization (dDDH) value between them was determined to be 35.4 %. Phenotypic, chemotaxonomic, phylogenetic, and genomic analyses suggested that strain WN019T represent a novel species of the genus Halorubrum, for which the name Halorubrum salipaludis sp. nov. is proposed. The type strain is WN019T (= KCTC 4269T = ACCC 19977T).
