Strain H2R21 T , a novel actinobacterium, isolated from a forest soil sample collected from Heybeliada, Istanbul, Turkey, and a polyphasic approach was used for characterisation of the strain. Chemotaxonomic and morphological characterisation of strain H2R21 T indicated that it belongs to the genus Nonomuraea. 16S rRNA gene sequence similarity showed that the strain is closely related to Nonomuraea purpurea 1SM4-01 T (99.1%) and Nonomuraea solani CGMCC 4.7037 T (98.4%). DNA–DNA relatedness values were found to be lower than 70% between the isolate and its phylogenetic neighbours N. purpurea 1SM4-01 T , N. solani CGMCC 4.7037 T and Nonomuraea rhizophila YIM 67092 T . The whole cell hydrolysates of strain H2R21 T were found to contain meso-diaminopimelic acid as the diagnostic diamino acid and glucose, madurose, mannose and ribose as the cell sugars. The polar lipids were identified as phosphatidylglycerol, diphosphatidylglycerol, phosphatidylmethylethanolamine, phosphatidylethanolamine, hydroxy-phosphatidylethanolamine, dihydroxy-phosphatidylethanolamine, phosphatidylinositol, glycophosphatidylinositol, two glycophospholipids and two unidentified lipids. The predominant menaquinones were identified as MK-9(H 4 ) and MK-9(H 6 ). The major fatty acids were found to be iso-C 16:0 , iso-C 16:0 2OH and C 17:0 10-methyl. On the basis of DNA–DNA relatedness data and some phenotypic characteristics, it is evident that strain H2R21 T can be distinguished from the closely related species in the genus Nonomuraea. Thus, it is concluded that strain H2R21 T represents a novel species of the genus Nonomuraea, for which the name Nonomuraea insulae sp. nov. is proposed. The type strain is H2R21 T (= DSM 102915 T = CGMCC 4.7338 T = KCTC 39769 T ).
