Abstract

A Gram-positive-staining bacterium, designated Y16, was isolated from a soil sample from Yunnan Province, China. The isolate grew optimally at 25–30 °C, grew at pH 6.0–9.0 and could grow with 3 % NaCl. Strain Y16 had cell-wall peptidoglycan based on -diaminopimelic acid. The predominant menaquinones were MK-9(H) and MK-9(H). The major fatty acid methyl esters were anteiso-C, iso-C, anteiso-C and C. These chemotaxonomic characteristics suggested that the organism belonged to the genus . Strain Y16 shared 98.7, 98.3 and 97.9 % 16S rRNA gene sequence similarity with IFO 13994, A4029 and DSM 43805, respectively. The DNA G+C content of the isolate was 70.8 mol%. DNA–DNA relatedness between the novel isolate and the type strains of , and was 35.2, 32.0 and 22.3 %, respectively. In addition, the pattern of phenotypic properties distinguished strain Y16 from its closest phylogenetic neighbours. It is therefore concluded that strain Y16 ( = CGMCC 4.6857 = JCM 17700) represents a novel species of the genus , for which the name sp. nov. is proposed.
