Acetobacter cerevisiae is a species of Gram negative acetic acid bacteria. Its type strain is LMG 1625<sup>T</sup> (= DSM 14362<sup>T</sup> = NCIB 8894<sup>T</sup> = ATCC 23765<sup>T</sup>).
The species was identified in 2002 by DNA-DNA hybridization as a group of related strains previously designated Acetobacter pasteurianus which were closely related to one another but not to other A. pasteurianus strains. These strains were all originally isolated from breweries.
