Quick Summary

Acetobacter refers to bacteria that play a crucial role in acetic fermentation. This is a process where alcohol is converted into acetic acid, a key step in producing vinegar from substances like cider or wine.1

Another related term is "acetic ferment," which describes any microorganism or enzyme capable of carrying out acetic fermentation. Additionally, "acetogens" are a type of anaerobic bacteria that can produce acetic acid from sugars or from carbon dioxide and hydrogen. These bacteria are of interest for their ability to synthesize acetic acid from biomass-derived sugars.23
