Reclassification of Amycolatopsis rugosa Lechevalier et al. 1986 as Prauserella rugosa gen. nov., comb. nov.

Abstract

An almost complete sequence of the 16S rDNA of the type strain of Amycolatopsis rugosa was determined following direct sequencing of the amplified gene. The sequence was aligned with those of representatives of the family Pseudonocardiaceae and related actinomycetes and phylogenetic trees were inferred by using three tree-making algorithms. The organism formed a distinct clade within the evolutionary radiation occupied by the family Pseudonocardiaceae. It was also readily distinguished from all of the validly described genera classified in this taxon by using a combination of chemical and morphological markers. On the basis of these genotypic and phenotypic differences, the name Prauserella gen. nov. is proposed for a new genus containing the previously misclassified Amycolatopsis rugosa. The type strain of Prauserella rugosa is DSM 43194(T) (= ATCC 43014(T) = NCIMB 8926(T)).
