Abstract

An aerobic, spore-forming, moderately halophilic bacterium, strain BH260, was isolated from a salt lake in China. Cells of this strain were found to be motile rods with flagella. The organism grew optimally at 30–32 °C and pH 8·0 in the presence of 12–15 % (w/v) NaCl. Phylogenetic analysis based on 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 for strain BH260 with respect to KCTC 3911, JCM 12147 and KCCM 41560 were 96·0, 95·5 and 95·3 %, respectively. Chemotaxonomic data (a DNA G+C content of 44 mol%; MK-7 as the major isoprenoid quinone; A1--diaminopimelic acid as the cell-wall type; phosphatidylglycerol and diphosphatidylglycerol as the major polar lipids; anteiso-C, anteiso-C and iso-C as the major fatty acids) also supported assignment of the isolate to the genus . On the basis of physiological and molecular properties, the isolate represents a novel species within the genus , for which the name sp. nov. is proposed. The type strain is BH260 (=KCTC 3915=DSM 16462).
