Abstract

A moderately halophilic bacterium, strain BH169, capable of growing at salinities of 3–20 % (w/v) NaCl was isolated from a saline lake in China. Strain BH169 was strictly aerobic, short-rod-shaped and non-motile (non-flagellated). Its major cellular fatty acids were anteiso-C, anteiso-C, iso-C and iso-C. The genomic DNA G+C content was about 43 mol% and the predominant quinone was MK-7. The cell-wall peptidoglycan was of the A1 type, containing -diaminopimelic acid as the diagnostic diamino acid. Phylogenetic analysis based on 16S rRNA gene sequences showed that the isolate formed a distinct phylogenetic line within the spore-forming rods of the genus . The levels of 16S rRNA gene sequence similarity to the type strains of species were below 93 %. On the basis of phenotypic and molecular properties, strain BH169 (=KCTC 3912=DSM 16461) represents the type strain of a novel species within the genus , for which the name sp. nov. is proposed.
