Abstract

Two novel species names, and , appeared on validation list no. 161 (January 2015) under priority numbers 26 and 28, respectively. As the published data suggested a high similarity of the organisms associated with these names, we aimed to define their taxonomic relationship. The study set included all strains used in the original nomenclatural proposals, i.e. 25 strains of and one strain of . The average nucleotide identity values (95.9 and 96.1 % based on and MUMmer, respectively) between the whole-genome sequences of ANC 3994 and KCTC 42081 supported the identity of these type strains at the species level. Based on the genus-wide comparative analyses of the sequences and whole-cell fingerprints generated by matrix-assisted laser desorption/ionization-time-of-flight MS, KCTC 42081 fell within the respective clusters formed by the 25 strains. The same picture was obtained on the basis of comparative analysis of 16S rRNA gene sequences of KCTC 42081 and three strains. Finally, the metabolic and physiological features of KCTC 42081 were found to be congruent with those of . Based on these results, we conclude that is a later heterotypic synonym of .
