A novel Gram-positive, motile, rod-shaped bacterium isolated from a saline soil in China was characterized by a polyphasic taxonomic approach. The strain, designated YC1, was halotolerant [tolerating up to 15 % (w/v) NaCl] and alkaliphilic (growing at a broad pH range of 5–13). 16S rRNA gene sequence analysis revealed that the isolate belonged to the genus , showing highest similarity to JCM 13285 (98.0 %). However, DNA–DNA hybridization indicated low levels of genomic relatedness with JCM 13285 (8.5 %). The major isoprenoid quinone was MK-7 and the cellular fatty acid profile consisted of significant amounts of iso-C (38.6 %) and anteiso-C (35.9 %). The predominant polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. The G+C content of the genomic DNA was 41.8 mol%. On the basis of the polyphasic evidence from this study, strain YC1 (=KCTC 13181=CGMCC 1.6854) should be classified as the type strain of a novel species of the genus , for which the name sp. nov. is proposed.
