© 2019, Springer Nature Switzerland AG.A novel actinobacterial strain, designated S2509T, was isolated from marine sediment collected by a dredge at a depth of 45 m along Melet River offshore of the southern Black Sea coast, Ordu, Turkey. The cell wall peptidoglycan of strain was found to contain meso-diaminopimelic acid and 3-OH-diaminopimelic acid. The whole cell sugars detected were arabinose, glucose, rhamnose, ribose and xylose. The diagnostic phospholipids of strain S2509T were found to be diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, a glycolipid and two unidentified phospholipids. The predominant menaquinones were identified as MK-9(H8), MK-9(H6), MK-10(H8), MK-9(H4), MK-10(H4) and MK-10(H6). The major cellular fatty acids were found to be iso-C16:0, iso-C15:0 and 10-methyl C17:0. The taxonomic position of the strain was established using a polyphasic approach, showing that S2509T strain belongs to the genus Micromonospora. Phylogenetic analysis based on the 16S rRNA gene sequence of strain S2509T showed that it is closely related to the type strain of Micromonospora chokoriensis DSM 45160T (99.37% sequence similarity), and phylogenetically clustered with Micromonospora inaquosa LB39T (99.37%), Micromonospora lupini Lupac 14NT (99.16%), Micromonospora violae NEAU-zh8T (99.23%) and Micromonospora taraxaci NEAU-P5T (99.03%). The phylogenetic analysis based on the gyrB gene sequence of strain S2509T confirmed its close relationship with M. chokoriensis JCM 13247T (96.5% sequence similarity). Whole genome sequences confirmed by digital DNA-DNA hybridization analysis that the strain S2509T represents a novel species in the genus Micromonospora, for which the name Micromonospora orduensis sp. nov. is proposed. The type strain is S2509T (=DSM 45926T = KCTC 29201T).
