Reclassification of Roseomonas fauriae Rihs et al. 1998 as a later heterotypic synonym of Azospirillum brasilense Tarrand et al. 1979

The relatedness of Roseomonas fauriae and Azospirillum brasilense was investigated using phenotypic methods and DNADNA hybridization. Conventional biochemical tests did not differentiate between the two taxa. DNADNA hybridization experiments revealed high values for relatedness between the type strains of these species and suggest that these two taxa constitute a single species. Strains previously identified as R. fauriae should be reclassified as A. brasilense, with the name Roseomonas fauriae as a later heterotypic synonym of Azospirillum brasilense.
