A polyphasic taxonomic study, including 16S rDNA sequence analysis, DNA-DNA
hybridizations, DNA base ratio determinations, amplified 16S rDNA restrict
ion analysis, whole-cell protein analyses and extensive biochemical charact
erization, was conducted to clarify the relationships of eight isolates fro
m root nodules of Mimosa species and one isolate from sputum of a cystic fi
brosis patient. All nine isolates were classified as a novel Ralstonia spec
ies, for which the name Ralstonia taiwanensis sp. nov. is proposed. The typ
e strain is LMG 19424(T) (= CCUG 44338(T)). R. taiwanensis effectively nodu
lated the Mimosa species and is the first beta -proteobacterium that is kno
wn to be capable of root nodule formation and nitrogen fixation.
