Abstract:
:The taxonomic position of a Gram-staining-positive strain, designated strain S4702T was isolated from a marine sediment collected from the southern Black Sea coast, Turkey, determined using a polyphasic approach. The isolate was found to have chemotaxonomic, morphological and phylogenetic properties consistent with its classification as representing a member of the genus Streptomyces and formed a distinct phyletic line in the 16S rRNA gene tree. S4702T was found to be most closely related to the type strains of Streptomyces marinus(DSM 41968T; 97.8 % sequence similarity) and Streptomyces abyssalis (YIM M 10400T; 97.6 %). 16S rRNA gene sequence similarities with other members of the genus Streptomyces were lower than 97.5 %. DNA-DNA relatedness of S4702T and the most closely related strain S. marinus DSM 41968T was 21.0 %. The G+C content of the genomic DNA was 72.5 mol%. The cell wall of the strain contained l,l-diaminopimelic acid and the cell-wall sugars were glucose and ribose. The major cellular fatty acids were identified as anteiso-C15 : 0, iso-C16 : 0, anteiso-C17 : 0 and iso-C15 : 0. The predominant menaquinone was MK-9(H8). The polar lipid profile of S4702T consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol and phosphatidylinositol mannoside. S4702T could be distinguished from its closest phylogenetic neighbours using a combination of chemotaxonomic, morphological and physiological properties. Consequently, it is proposed that S4702T represents a novel species of the genus Streptomyces, for which the name Streptomyces ovatisporus sp. nov. is proposed. The type strain is S4702T (DSM 42103T=KCTC 29206T=CGMCC 4.7357T).
