Abstract

The taxonomic position of acidophilic actinomycetes selectively isolated from acidic soils and litter was examined using a polyphasic approach. The distinct 16S rDNA phyletic branch formed by representative strains was equated with related monophyletic clades that corresponded to the genera Kitasatospora and Streptomyces. The acidophilic isolates also exhibited a distinctive pH profile, a unique 16S rDNA signature, and contained major amounts of LL-diaminopimelic acid, galactose and rhamnose in whole-organism hydrolysates. It is proposed that these acidophilic actinomycetes be assigned to a new genus, Streptacidiphilus gen. nov., on the basis of genotypic and phenotypic differences. Three species were defined on the basis of DNA:DNA pairing and phenotypic data, namely, Streptacidiphilus albus sp. nov., the type species, Streptacidiphilus neutrinimicus sp. nov. and Streptacidiphilus carbonis sp. nov. Members of the genera Kitasatospora, Streptacidiphilus and Streptomyces share a number of key characteristics and form a stable monophyletic branch in the 16S rDNA tree. It is, therefore, proposed that the description of the family Streptomycetaceae be emended to account for properties shown by Kitasatospora and Streptacidiphilus species.
