The taxonomic position of three acidophilic actinomycetes isolated from acidic rhizosphere soil was established using a polyphasic approach. The morphological and chemical properties of the isolates were found to be consistent with their assignment to the genus Streptacidiphilus. Almost complete 16S rRNA gene sequences determined for the strains were aligned with corresponding sequences of representatives of the genera Kitasatospora, Streptacidiphilus and Streptomyces and phylogenetic trees inferred using three tree-making algorithms. The organisms formed a distinct subclade within the Streptacidiphilus 16S rRNA gene tree. They also shared nearly identical phenotypic profiles and rep-PCR fingerprint patterns that readily distinguished them from representatives of the established species of Streptacidiphilus. It is evident from the genotypic and phenotypic data that the three isolates form a new species in the genus Streptacidiphilus. The name proposed for this new species is Streptacidiphilus jiangxiensis, the type strain is isolate 33214T (= AS 4.1857T = JCM 12277T).
