The GenBank/EMBL/DDBJ accession numbers for the 16S rRNA gene sequences of strains NB53 T , NB446 T and NB702 are AB907190, AB907192 and AB907193, respectively; those of the dnaK gene sequences are AB907195, AB907197 and AB907198; those of the pheS gene sequences are AB907205, AB907207 and AB907208; those of the rpoA gene sequences are AB907209, AB907211 and AB907212; and those of the recA gene sequences are AB983473, AB983474 and AB983475.

One is the genus Gluconacetobacter, in which the type species is retained as Gluconacetobacter liquefaciens (Asai 1935) Yamada et al. 1998, and the other is the genus Komagataeibacter Yamada et al. 2013, in which the type species is newly designated as Komagataeibacter xylinus (Brown 1898) Yamada et al. 2013. In the genus Gluconacetobacter, seven species are nowadays accommodated (
