Genus: Acetobacter

[= Gluconacetobacter]

Bacteria > Proteobacteria > Alphaproteobacteria > Rhodospirillales > Acetobacteraceae

Acid-producing, nitrogen-fixing bacteria that are associated with plants. They are able to fix atmospheric nitrogen under aerobic (oxygen present) conditions. Acetobacter also plays a role in the fermentation of vinegar from rice (komesu in Japanese).

Ecological relationships

Acetobacter diazotrophicus has been found as a beneficial, nitrogen-fixing symbiotic endophyte in the following plants. Judging by the wide range of hosts, it is probably found in many other plant species as well. There are other species of Acetobacter that have not been studied in such detail.
