Oval-shaped, short rods. Gram-stain-positive. Motile. Endospores not formed. Strictly anaerobic. Optimal temperature 27–30°C for mesophilic species, 20–30°C for psychrotolerant species. Optimal pH 7.0–8.0. Colonies are convex, white, slightly yellow, or brownish, 0.6–1.0 mm in diameter. Autotrophic growth occurs by anaerobic oxidation of H2 and reduction of CO2 to acetic acid. Chemo-organotrophic, carrying out homoacetogenic fermentation of reduced substrates, such as fructose and some other monomeric sugars, as well as pyruvate, lactate, glycerol, and methanol; methyl groups of phenyl methyl ethers and betaine are converted to acetate. The acetyl-CoM pathway serves as an energy-conserving process and as a mechanism for autotrophic assimilation of carbon. Cytochromes have not been detected.

DNA G + C content (mol%): 39–45.8.

Type species: Acetobacterium woodii Balch, Schoberth, Tanner and Wolfe 1977, 360.
