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.
