Acetobacteraceae is a family of Gram-negative bacteria, belonging to the order Rhodospirillales, class Alphaproteobacteria. Two distinct clades are recognized: the acetic acid bacteria and a more heterogeneous group including acidophilic and phototrophic bacteria. The type genus is Acetobacter. Ten genera from Acetobacteraceae make up the acetic acid bacteria.
Acetobacteraceae was originally proposed as a family for Acetobacter and Gluconobacter based on rRNA and DNAâÂÂDNA hybridization comparisons in 1980.
