title: Transfer of Wautersia numazuensis to the genus Cupriavidus as Cupriavidus numazuensis comb. nov.
abstract: Phylogenetic analysis of the 16S rRNA gene sequences of strains TE26(T) and K6 belonging to Wautersia numazuensis Kageyama et al. 2005 showed the strains to be deeply intermingled among the species of the genus Cupriavidus. The comparison showed that strain TE26(T) was closely related to the type strains of Cupriavidus pinatubonensis (99.1 % 16S rRNA gene sequence similarity), C. basilensis (98.7 %), C. necator (98.7 %) and C. gilardii (98.0 %). However, DNA-DNA hybridization experiments (less than 20 % relatedness) demonstrated that strain TE26(T) is different from these Cupriavidus species. A comparative phenotypic and chemotaxonomic analysis (based on fatty acid profiles) in combination with the 16S rRNA gene sequence phylogenetic analysis and the DNA-DNA hybridization results supported the incorporation of Wautersia numazuensis into the genus Cupriavidus as Cupriavidus numazuensis comb. nov.; the type strain is TE26(T) (=LMG 26411(T) =DSM 15562(T) = CIP 108892(T)).
