title: Streptomyces araujoniae sp. nov.: an actinomycete isolated from a potato tubercle.
abstract: The taxonomic position of a streptomycete isolated from a potato tubercle was determined by using a polyphasic approach. The organism had chemotaxonomic and morphological properties consistent with its classification in the genus Streptomyces and formed a distinct phyletic line in the Streptomyces 16S rRNA gene tree. It was found to be closely related to Streptomyces celluloflavus NRRL B-2493(T) (99.4 % 16S rRNA gene similarity) and shared a 99.0 % 16S rRNA gene similarity value with Streptomyces albolongus NRRL B-3604(T) and Streptomyces cavourensis subsp. cavourensis NBRC 13026(T); low levels of DNA-DNA relatedness with these organisms showed that the isolate belonged to a distinct genomic species. The isolate was distinguished readily from the type strains of these species using a combination of morphological and other phenotypic properties. On the basis of these results, it is proposed that isolate ASBV-1(T) (= CBMAI 1465(T) = CCMA 894(T) = NRRL B-24922(T)) be classified as the type strain of Streptomyces araujoniae sp. nov.
