title: Bacillus shacheensis sp. nov., a moderately halophilic bacterium isolated from a saline-alkali soil.
abstract: A moderately halophilic bacterium, strain HNA-14(T), was isolated from a saline-alkali soil sample collected in Shache County, Xinjiang Province. On the basis of the polyphasic taxonomic data, the isolate was considered to be a member of the genus Bacillus. The organism grew optimally at 30 °C and pH 8.0. It was moderately halophilic and its optimum growth occurred at 5-10% NaCl. The diamino acid found in the cell-wall peptidoglycan was meso-diaminopimelic acid and the predominant menaquinone was MK-7. The major cellular fatty acids were anteiso-C15:0 and iso-C15:0 and the polar lipid profile consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannosides and two unknown phospholipids. The G+C content of the genomic DNA was 48.6 mol%. Strain HNA-14(T) exhibited a low 16S rRNA gene sequence similarity of 96% with its nearest neighbors [Bacillus clausii KSM-K16 (96.5%), Bacillus xiaoxiensis DSM 21943(T)(96.2%), Bacillus clausii DSM 8716(T) (96.1%), Bacillus patagoniensis PAT05(T) (96.1%), Bacillus lehensis MLB-2(T) (96.0%), Bacillus oshimensis K11(T) (95.9%) and Bacillus hunanensis DSM 23008(T) (95.8%)] and the phenotypic characteristics indicate that strain HNA-14(T) can be distinguished from them. Therefore, a novel species of the genus Bacillus, Bacillus shacheensis sp. nov. (type strain, HNA-14(T) = KCTC 33145 = DSM 26902) is proposed.
