The taxonomic position of actinomycete, strain NR4-ASC07T isolated from soil sample collected from Sirindhorn peat swamp forest, Narathiwat Province, Thailand, was clarified using a polyphasic approach. On the basis of morphological and chemotaxonomic characteristics, it was classified in the members of the genus Nonomuraea. It produced tightly closed spiral spore chains on aerial mycelium as well as forming the pseudosporangium. Whole-cell hydrolysate contained meso-diaminopimelic acid, glucose, ribose, madurose and mannose. The polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, hydroxyphosphatidylethanolamine, lyso-phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannosides, unknown ninhydrin-positive phosphoglycolipids and unknown glycolipid. Menaquiones were MK-9(H4), MK-9(H0), MK-9(H2), MK-10(H4) and MK-9(H6). Predominant cellular fatty acids were iso-C16:0, C17:0 10-methyl, C16:0, C17:1ω8c, C16:0 2-OH and iso-C15:0. The phylogenetic tree constructed based on the 16S rRNA gene sequences showed the strain fell within the clade of Nonomuraea muscovyensis FMN03T, Nonomuraea roseoviolacea subsp. roseoviolacea IFO 14098T and Nonomuraea roseoviolacea subsp. carminata IFO 15903T. The DNA-DNA relatedness and phenotypic data supported that strain NR4-ASC07T was clearly distinguished from its closely related species and represents the novel species of the genus Nonomuraea for which the name Nonomuraea rhodomycinica is proposed. The type strain is NR4-ASC07T (= NBRC 112327T = TISTR 2465T).
