title: Saccharothrix tamanrassetensis sp. nov., an actinomycete isolated from Saharan soil.
abstract: Actinomycete strain SA198(T), isolated from a Saharan soil sample of Algeria, was characterized taxonomically by using a polyphasic approach. Chemotaxonomic and morphological characteristics observed suggested that it was a member of the genus Saccharothrix . The 16S rRNA gene sequence analysis confirmed that strain SA198(T) was a member of the genus Saccharothrix and showed a similarity level ranging between 97.5 and 98.9% within species of the genus Saccharothrix , Saccharothrix australiensis being the most closely related. However, DNA-DNA hybridization values between strain SA198(T) and its closest phylogenetic neighbours, the type strains of S. australiensis , Saccharothrix xinjiangensis , Saccharothrix algeriensis and Saccharothrix espanaensis , were clearly below the 70% threshold. Based upon genotypic and phenotypic differences from other members of the genus, a novel species, Saccharothrix tamanrassetensis sp. nov., is proposed, with SA198(T) ( = DSM 45947(T) = CECT 8640(T)) as the type strain.
