Abstract

Two Gram-positive, motile, rod-shaped, halophilic bacteria showing optimum growth at 5–7 % (w/v) NaCl were isolated from a salt lake, Xin-Jiang Province, China. The strains, designated BH312 and BH314, grew in the presence of 1–18 % (w/v) NaCl and at temperatures of 15–50 °C (optimum: 40 °C) and pH values of 5.5–10.0 (optimum: pH 7.5–8.0). The major cellular fatty acids were anteiso-C, iso-C and anteiso-C. The DNA G+C content was 38.8–39.0 mol% and the predominant lipoquinone was MK-7. The major cellular phospholipids were phosphatidylglycerol, diphosphatidylglycerol and two unidentified phospholipids. Phylogenetic analyses based on 16S rRNA gene sequences showed that the isolates formed a cluster with XH-63 within the genus . The levels of 16S rRNA gene sequence similarity with closely related type strains were lower than 96.2 %. On the basis of phylogenetic, phenotypic and chemotaxonomic properties, the isolates represent a novel species of the genus for which the name sp. nov. is proposed. The type strain is BH312 (=KCTC 13129=DSM 19029).
