Taxonomic position of "Pseudomonas oxalaticus" strain ox14T (DSM 1105T) (Khambata and Bhat, 1953) and its description in the genus Ralstonia as Ralstonia oxalatica comb. nov.
"Pseudomonas oxalaticus" strain Ox1T (= DSM 1105T), 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 Ox1T 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 Ox1T, on the basis of these results and previously published data for the G+C content of the genomic DNA and the phenotypic characters.
