Three strains of actinomycetes that formed spore chains were isolated from a paddy field and forest soil and subjected to a polyphasic taxonomic characterization study. The cell wall peptidoglycan contained -diaminopimelic acid and glycine. The major isoprenoid quinones were MK-9(H) and MK-9(H), and the major cellular fatty acids were iso-C and anteiso-C. Phylogenetic analysis based on 16S rRNA gene sequences showed that these organisms belonged in a monophyletic cluster with members of the genus . According to the physiological, biochemical and chemotaxonomic data, the novel organisms could be differentiated from recognized members of the genus . Based on the phenotypic and genotypic data, the three strains are considered to represent two novel species of the genus , for which the names sp. nov. for strains TT 99-48 (type strain; =NBRC 103395=KCTC 19328) and TT 01-19 (=NBRC 103396), and sp. nov. (type strain TT N02-20=NBRC 103397=KCTC 19327) are proposed. An emended description of the genus is given.
