'Pseudomonas oxalaticus' strain Ox1(T) (= DSM 1105(T)), which was described as an oxalate-decomposing bacterium, was reinvestigated to clarify its taxonomic position. 16S ribosomal DNA sequence comparisons demonstrated that this species is phylogenetically related to the species of the genus Ralstonia and represents a new species. The result of the DNA-DNA hybridization value was supported in this placement. Strain Ox1(T) is closely related to Ralstonia eutropha with a less than 60% DNA-DNA hybridization value. The new name Ralstonia oxalatica comb. nov. is proposed to strain Ox1(T), on the basis of these results and previously published data for the G + C content of the genomic DNA and the phenotypic characters.
