ABSTRACT
A novel actinobacteria, isolate A7024T, was isolated from commercial hazelnut orchard soil sample which was collected at Duzce, West Black Sea region, Turkey. A polyphasic taxonomic study was carried out to determine the status of this isolate. The phylogenetic tree reconstructed using the neighbour-joining algorithm based on 16S rRNA gene sequences indicated that isolate A7024T was positioned within the members of the genus Streptomyces with the highest sequence similarity (97.7â%) to Streptomyces cadmiisoli ZFG47T. The organism formed an extensively branched substrate and aerial hyphae which generated irregular rod-shaped spores with smooth-surfaces. The cell wall of strain A7024T contained ll-diaminopimelic. Glucose, mannose and ribose were detected as whole-cell sugars. Its polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, three unidentified phospholipids and three unidentified glycolipids. Major menaquinones were MK-9(H6) and MK-9(H4). The major cellular fatty acids were iso-C16ââ0, anteiso-C15ââ0 and anteiso-C17ââ0. Strain A7024T had a genome size of 9.0 Mb with a genome G+C content of 71.5 mol%. The low level of 16S rRNA gene similarity, 19.3 ± 2.3% digital DNA-DNA hybridization and 76.94â% average nucleotide identity values, as well as some different phenotypic characteristics allowed the strain to be distinguished from the closely related type strains. Therefore, it is concluded that strain A7024T represents a novel species of the genus of Streptomyces, for which the name Streptomyces coryli sp. nov. is proposed. The type strain is A7024T (=DSM 42066T=KCTC 29102T=NRRL B-24888T).
