All strains were shown to belong to the Ralstonia branch of the beta-Proteobacteria. Whole-cell protein profiles and DNA-DNA hybridizations revealed two clearly distinct groups, showing low similarity to known Ralstonia species. These two groups, of 8 and 17 isolates, were assigned to two new species, for which the names Ralstonia campinensis sp. nov. and Ralstonia metallidurans sp. nov. are proposed. The type strains are WS2T (= LMG 19282T = CCUG 44526T) and CH34T (= LMG 1195T = DSM 2839T), respectively. Six isolates were allocated to Ralstonia basilensis, which presently contains only the type strain; an emendation of the latter species description is therefore proposed., language=, type=
