Abstract

A novel actinomycete strain, YIM 001, was isolated from a soil sample collected from Hebei province, People's Republic of China. The strain was characterized by white to grey aerial mycelium. Long spore chains, borne on the aerial mycelium, were straight to ; the spore chains were composed of non-motile and coccoid spores with a warty surface. The cell wall of strain YIM 001 contained -diaminopimelic acid (Apm) and traces of -Apm. Whole-cell hydrolysates contained mainly glucose and small amounts of xylose, galactose and arabinose. The menaquinones were MK-9(H) (4·6 %), MK-9(H) (60 %), MK-9(H) (30·7 %) and MK-9(H) (4·7 %). Phosphatidylethanolamine was the diagnostic phospholipid. The DNA G+C content of strain YIM 001 was 71·4 mol%. Phylogenetic analysis indicated that strain YIM 001 belongs to the genus . Based on its phenotypic and genotypic characteristics, strain YIM 001 (=CCTCC AA 203005=CIP 107974=DSM 41837) is proposed as the type strain of a novel species, sp. nov.
