A moderately halophilic, Gram-positive coccus, designated strain W24, was isolated from saline soil in Qinghai province, China. The isolate was able to grow at salinities of 0–24 % (w/v) NaCl (optimally at 8 %, w/v), at pH 5.5–9.0 (optimally at pH 7.5) and at 8–43 °C (optimally at 28 °C). The genomic DNA G+C content of strain W24 was 45.8 mol%. The predominant isoprenoid quinone was MK-6 and the cell wall contained lysine and glycine as diagnostic diamino acids. The polar lipids were diphosphatidylglycerol, phosphatidylglycerol and an unidentified glycolipid. The major cellular fatty acids were iso-C, anteiso-C and C. Based on 16S rRNA gene sequence analysis, strain W24 was found to be a member of the genus and was related most closely to DSM 5352 (96.5 % sequence similarity). Based on data from the current polyphasic study, strain W24 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is W24 (=CGMCC 1.6501=DSM 19336).
