Abstract

Bacteria isolated from onion bulbs suffering from bacterial decay in the United States and Norway were previously shown to belong to the genus Rahnella based on partial housekeeping gene sequences and/or fatty acid analysis. However, many strains could not be assigned to any existing Rahnella species. Additionally, strains isolated from creek water and oak as well as a strain with bioremediation properties were assigned to Rahnella based on partial housekeeping gene sequences. The taxonomic status of these 21 strains was investigated using multilocus sequence analysis, whole genome analyses, phenotypic assays and fatty acid analysis. Phylogenetic and phylogenomic analyses separated the strains into five clusters, one of which corresponded to Rahnella aceris. The remaining four clusters could be differentiated both genotypically and phenotypically from each other and existing Rahnella species. Based on these results, we propose the description of four novel species: Rahnella perminowiae sp. nov. (type strain SL6T = LMG 32257T = DSM 112609T), Rahnella bonaserana sp. nov. (type strain H11bT = LMG 32256T = DSM 112610T), Rahnella rivi sp. nov. (type strain FC061912-KT = LMG 32259T = DSM 112611T) and Rahnella ecdela sp. nov. (type strain FRB 231T = LMG 32255T = DSM 112612T).
