Saccharopolyspora flava sp nov and Saccharopolyspora thermophila sp nov., novel actinomycetes from soil

The generic position of two aerobic, Cram-positive, non-acid-alcohol-fast actinomycetes was established following the isolation of their PCR-amplified 16S rRNA genes and alignment of the resultant sequences with the corresponding sequences from representatives of the families Actinosynnemataceae and Pseudonocardiaceae. The assignment of the organisms to the genus Saccharopolyspora was strongly supported by chemotaxonomic and morphological data. The strains were distinguished both from one another and from representatives of validly described Saccharopolyspora species on the basis of a number of phenotypic properties. It is proposed that the organisms, strains 07(T) (= AS4.1520(T) = IFO 16345(T)= JCM 10665(T)) and 216(T)(= AS4.1511(T) = IFO 16346(T) = JCM 10664(T)), be classified in the genus Saccharopolyspora as Saccharopolyspora flava sp, nov. and Saccharopolyspora thermophila sp, nov., respectively.
