Özet

During the course of isolating rare actinobacteria from unexplored habitats, strain CH32T was obtained from an arid soil sample in eastern Anatolia, Turkey. Polyphasic characterization and comprehensive genome analyses showed that the strain is a member of the genus Nonomuraea and it is closely related to Nonomuraea gerenzanensis ATCC 39727T, Nonomuraea polychroma DSM 43925T and Nonomuraea maritima FXJ7.203T with gene identity level of 98.7%, 98.2% and 98.1%, respectively. The whole-cell hydrolysates contain meso-diaminopimelic acid as diagnostic diaminoacid and glucose, ribose, galactose, mannose and madurose as whole cell sugars. The predominant menaquinones are MK-9(H4), MK-9(H6) and MK-9(H2) while MK-9 exists as minor component. The polar lipid profile consists of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol, glycolipid, glycophospholipids, phospholipids and unidentified lipids. The major cellular fatty acids are iso-C16:0 and C17:0 10-methyl. The total genome size is about 9.6 Mb and the G + C content is 71.0%. The genome contains biosynthetic gene clusters encoding for terpenes, siderophores, a type III polyketide synthase, a non-ribosomal polypeptide synthetase and a bacteriocin. The genome-based comparisons of the strain with its phylogenetic neighbours, as indicated by digital DNA–DNA hybridization and average nucleotide identity analyses, reveal that strain CH32T (= JCM 33876T = KCTC 49368T) is a novel member of the genus Nonomuraea, for which Nonomuraea terrae sp. nov. is proposed.
