A novel actinomycete strain, YIM 001T, 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 Rectiflexibiles; the spore chains were composed of non-motile and coccoid spores with a warty surface. The cell wall of strain YIM 001T contained LL-diaminopimelic acid (A2pm) and traces of meso-A2pm. Whole-cell hydrolysates contained mainly glucose and small amounts of xylose, galactose and arabinose. The menaquinones were MK-9(H4) (4·6 %), MK-9(H6) (60 %), MK-9(H8) (30·7 %) and MK-9(H10) (4·7 %). Phosphatidylethanolamine was the diagnostic phospholipid. The DNA G+C content of strain YIM 001T was 71·4 mol%. Phylogenetic analysis indicated that strain YIM 001T belongs to the genus Streptomyces. Based on its phenotypic and genotypic characteristics, strain YIM 001T (=CCTCC AA 203005T=CIP 107974T=DSM 41837T) is proposed as the type strain of a novel species, Streptomyces hebeiensis sp. nov.
The GenBank/EMBL/DDBJ accession number for the 16S rDNA sequence of strain YIM 001T is AY277529.
