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 001 T contained LL -diaminopimelic acid (A 2 pm) and traces of meso -A 2 pm. Whole-cell hydrolysates contained mainly glucose and small amounts of xylose, galactose and arabinose. The menaquinones were MK-9(H 4 ) (4·6 %), MK-9(H 6 ) (60 %), MK-9(H 8 ) (30·7 %) and MK-9(H 10 ) (4·7 %). Phosphatidylethanolamine was the diagnostic phospholipid. The DNA G+C content of strain YIM 001 T was 71·4 mol%. Phylogenetic analysis indicated that strain YIM 001 T belongs to the genus Streptomyces . Based on its phenotypic and genotypic characteristics, strain YIM 001 T (=CCTCC AA 203005 T =CIP 107974 T =DSM 41837 T ) is proposed as the type strain of a novel species, Streptomyces hebeiensis sp. nov.
