description

In a previous article [Oggerin M., Arahal, D. R., Rubio, V. & Marin, I. (2009). Int J Syst Evol Microbiol 59, 2323–2328], it has been shown that strain Beijerinckia fluminensis UQM 1685T and its derived equivalent B. fluminensis CIP 106281T do not conform to the description of the type strain of Beijerinckia fluminensis Döbereiner and Ruschel 1958. Indeed, both strains were identified as members of the species Rhizobium radiobacter and exhibited marked phenotypic and genotypic differences with members of the genus Beijerinckia. It was concluded that both strains, and any other equivalents derived from them, do not descend from the nomenclatural type. Since then, our attempts to find older deposits of the type strain, hopefully derived from the original isolate, or other existing strains of Beijerinckia fluminensis that could be proposed as a neotype strain, have been in vain. It is therefore proposed that the Judicial Commission should place the name Beijerinckia fluminensis Döbereiner and Ruschel 1958 on the list of rejected names if a suitable replacement type strain or a neotype cannot be found within two years following the publication of this Request (Rule 18c).
