Abstract

The taxonomic position of ten acidophilic actinomycetes isolated from an acidic rice-field soil was established using a polyphasic approach. 16S rRNA gene sequences determined for the isolates were aligned with corresponding sequences of representatives of the genera , and and phylogenetic trees were inferred using four tree-making algorithms. The isolates had identical sequences and formed a distinct branch at the periphery of the 16S rRNA gene tree. The chemotaxonomic and morphological properties of representative isolates were consistent with their assignment to the genus . The isolates shared nearly identical phenotypic profiles that readily distinguished them from representatives of the established species of . It is evident from the genotypic and phenotypic data that the isolates form a homogeneous group that corresponds to a novel species in the genus . The name proposed for this new taxon is sp. nov.; the type strain is strain TH49 (=CGMCC 4.2012=JCM 13271).
