ABSTRACT
A Gram-stain-positive, rod-shaped, endospore-forming, halophilic, alkalitolerant bacterium, designated halo-1(T), was isolated from sediment of Xiarinaoer soda lake, located in the Inner Mongolia Autonomous Region of China. Strain halo-1(T) grew in the presence of 9-30 % (w/v) NaCl (optimum 19 %) and at pH 5-10 (optimum pH 9). The cell-wall peptidoglycan contained meso-diaminopimelic acid and the major respiratory isoprenoid quinone was MK-7. The predominant cellular fatty acids of the isolate were anteiso-C(15 0) (58.35 %), anteiso-C(17 0) (12.89 %) and C(16 0) (6.52 %). The polar lipids contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, glycolipid and a phospholipid of unknown structure. The DNA G+C content of the strain was 46.4 mol%. On the basis of 16S rRNA gene sequence similarity, strain halo-1(T) showed the highest similarity (93.9 %) to Salsuginibacillus kocurii CH9d(T). Strain halo-1(T) could be clearly differentiated from its closest phylogenetic relative on the basis of several phenotypic, genotypic and chemotaxonomic features. Therefore, strain halo-1(T) represents a novel species, for which the name Salsuginibacillus halophilus sp. nov. is proposed, with the type strain halo-1(T) (=CGMCC 1.7653(T) =NBRC 104934(T)).
