A novel Gram-positive, rod-shaped actinobacterium, designated strain YIM 90718T, was isolated from a saline soil in Xinjiang province, north-west China, and subjected to polyphasic taxonomy. The peptidoglycan type was A1γ and the cell-wall sugars contained galactose. Phospholipids were phosphatidylglycerol and diphosphatidylglycerol. The predominant menaquinone was MK-8(H2). The major fatty acids were anteiso-C15 : 0, anteiso-C17 : 0 and iso-C15 : 0. All of these chemotaxonomic data assigned the new isolate YIM 90718T consistently to the genus Brevibacterium. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain YIM 90718T formed a distinct phyletic lineage in the genus Brevibacterium and showed the highest sequence similarity (96.2 %) to Brevibacterium samyangense SST-8T and low similarity (<95.5 %) to other species of the genus Brevibacterium. On the based of the polyphasic evidence, a novel species, Brevibacterium album sp. nov., is proposed, with the type strain YIM 90718T (=DSM 18261T =KCTC 19173T =CCTCC AB 206112T).
