| Abstract |
A Gram-positive, strictly aerobic, non-motile, milky-white to creamy coloured and rod-shaped bacterium, designated BS05T, was isolated from compost. Phylogenetic analysis based on 16S rRNA gene sequence comparison revealed that the strain formed a distinct lineage within the genus Brevibacterium and was most closely related to Brevibacterium avium NCFB 3055T (96.3 %), Brevibacterium oceani BBH7T (96.2 %) and Brevibacterium epidermidis NBRC 14811T (96.1 %). The DNA G+C content was 62.3 mol%. The predominant quinone was MK-8(H2). The major fatty acids were anteiso-C15 : 0, anteiso-C17 : 0, iso-C16 : 0 and iso-C15 : 0. The cell-wall peptidoglycan of strain BS05T contained meso-diaminopimelic acid. The major polar lipid was phosphatidylglycerol. Moreover, the low sequence similarity of the 16S rRNA gene sequencing, physiological, biochemical and chemotaxonomic analyses allowed the phenotypic and genotypic differentiation of strain BS05T from the recognized species of the genus Brevibacterium. Therefore, strain BS05T represents a novel species of the genus Brevibacterium, for which the name Brevibacteriumhankyongi sp. nov. is proposed, with the type strain BS05T (=KACC 18875T=LMG 29562T).
