Actinomycete strain TT1-11T, which produces single non-motile spores on substrate hyphae, was isolated from peat swamp forest soil in Thailand. The isolate showed morphological and chemotaxonomic properties consistent with its classification in the genus Micromonospora. Phylogenetic analysis using 16S rDNA sequences supported this assignment and it formed a subclade with M. coerulea. This isolate can be distinguished from M. coerulea by its physiological and biochemical properties, and it showed a less than 53% DNA relatedness to the type strains of all the validly named Micromonospora species. On the basis of phenotypic, genotypic and phylogenetic data, strain TT1-11T (=JCM 12357T =PCU 239T =DSM 44815T=TISTR 1232T) is proposed as the type strain of a novel Micromonospora species, Micromonospora aurantionigra sp. nov.
