Streptomyces thermospinisporus sp. nov., a moderately thermophilic carboxydotrophic streptomycete isolated from soil.

A carboxydotrophic actinomycete strain, AT10T (= DSM 41779T = KCTC 9909T), was the subject of a polyphasic study. The morphological and chemical properties of the strain were found to be consistent with its assignment to the genus Streptomyces. The organism formed a distinct phyletic line within the 16S rDNA Streptomyces tree, and DNA-DNA relatedness experiments further confirmed that it formed a distinct genomic species. The strain was also distinguished from related species using phenotypic properties. Strain AT10T, therefore, merits species status within the genus Streptomyces; the name Streptomyces thermospinisporus sp. nov. is proposed for this new taxon.
