Abstract

A Gram-positive, moderately halophilic bacterium, designated strain BH113, was isolated from a salt lake located in Xinjiang Province, China. Cells of the strain were aerobic, spore-forming, motile rods with flagella. The organism grew optimally at 37 °C and pH 8.0 in the presence of 10 % (w/v) NaCl. A phylogenetic analysis based on comparisons of 16S rRNA gene sequences showed that the isolate formed a clade with the type strains of the genus . The levels of 16S rRNA gene sequence similarity between strain BH113 and KCTC 3915, JCM 12147 and JCM 12580 were 96.7, 96.3 and 96.1 %, respectively. The G+C content of the genomic DNA was 46.2 mol% and the major isoprenoid quinone was MK-7. The peptidoglycan type was A1 (-diaminopimelic acid) and the major polar lipids were phosphatidylglycerol and diphosphatidylglycerol. The major fatty acids were anteiso-C, iso-C and anteiso-C. Therefore, on the basis of physiological, chemotaxonomic and molecular properties, strain BH113 represents a novel species within the genus , for which the name sp. nov. is proposed. The type strain is BH113 (=KCTC 3936 =DSM 16817).
