| Abstract: | A novel actinomycete strain, designated YIM 45720T, was isolated from a Cephalotaxus fortunei rhizophere soil sample collected from Yunnan Province, southwest China. The strain formed well-differentiated aerial and
substrate mycelia. Chemotaxonomically, it contained LL-diaminopimelic acid in the cell wall. The cell-wall sugars contained
ribose, mannose, and galactose with traces of glucose and xylose. Phospholipids were diphosphatidylglycerol, phosphatidylethanolamine,
phosphatidylcholine and phosphatidylinositol. MK-9 (H8) was the predominant menaquinone. The major fatty acids (>10%) were iso-C16:0, iso-C15:1 and anteiso-C15:0. The G + C content of the DNA was 70 mol%. Phylogenetic analysis data based on 16S rRNA gene sequence showed that strain YIM 45720T formed a distinct branch with the type strain of Streptomyces scabrisporus JCM 11712T within the genus Streptomyces. On the basis of the phenotypic and genotypic characteristics, strain YIM 45720T (=DSM 41883T = CCTCC AA 206006T) is proposed as the type strain of a novel species, Streptomyces serianimatus sp. nov. |
