abstract= A novel Gram-stain-negative, slightly halophilic, motile, curved rod with a horseshoe shape, designated strain Bsw-2bT, was isolated from Badab-Soort travertine spring in Iran. Phylogenetic analysis of the 16S rRNA gene sequence revealed that strain Bsw-2bT belongs to the order Balneolales , showing 84.6 % sequence similarity to Gracilimonas tropica DSM 19535T and 84.4 % and 83.9 % sequence similarity to Gracilimonas rosea CL-KR2T and Balneola vulgaris DSM 17893T, respectively. In addition, phenotypic and physiological features could clearly differentiate strain Bsw-2bT from species of the most closely related genera, Gracilimonas , Balneola , Aliifodinibius and Fodinibius . The strain was able to grow with 1–3 % (w/v) (optimum at 2 %) NaCl, at temperatures of 28–34 °C (optimum at 30 °C) and between pH 6.0 and 8.0 (optimum at pH 7.0). The major cellular fatty acids of strain Bsw-2bT were iso-C15 : 0, iso-C13 : 0 and iso-C14 : 0. The polar lipid profile of strain Bsw-2bT was composed predominantly of phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, an unknown glycolipid and four unknown phospholipids. The DNA G+C content was 40.5 mol%. Based on the evidence from the polyphasic study, strain Bsw-2bT represents a novel species in a novel genus within a new family, for which the name Soortia roseihalophila gen. nov., sp. nov. is proposed, within the new family Soortiaceae fam. nov. The type strain is strain Bsw-2bT (=IBRC-M 10915T=LMG 28547T).,
