Acetobacter aceti is a Gram-negative bacterium that moves using its peritrichous flagella. Louis Pasteur proved it to be the cause of conversion of ethanol to acetic acid in 1864. It is a benign microorganism which is present everywhere in the environment, existing in alcoholic ecological niches which include flowers, fruits, and honey bees, as well as in water and soil. It lives wherever sugar fermentation occurs. It grows best in temperatures that range from 25 to 30 degrees Celsius and in pH that ranges from 5.4 to 6.3. For a long time it has been used in the fermentation industry to produce acetic acid from alcohol. Acetobacter aceti is an obligate aerobe, which means that it requires oxygen to grow.

L'Acetobacter aceti è un microrganismo acidofilo resistente perfino a pH 0. È un batterio aerobio obbligato, Gram - negativo, mobile grazie alla presenza di flagelli peritrici in grado di tollerare una concentrazione di etanolo del 10% (è pertanto il maggior responsabile delle ossidazioni dei vini a basso grado alcolico). La temperatura ottimale è compresa tra 25 e 30 °C, il pH ideale tra 5,4 e 6,3. In natura occupa le nicchie ecologiche nelle quali si sviluppa alcol in seguito a fermentazione degli zuccheri, come fiori, frutti, favi di api, ma può essere rinvenuto anche nel suolo o nelle acque.Attualmente sono descritte 4 sottospecie di Acetobacter aceti:

Acetobacter aceti is een soort van azijnzuurbacteriën behorende tot het geslacht Acetobacter. Acetobacter aceti is de typesoort van het geslacht. De bacterie is gramnegatief en beweegt zich voort door middel van een flagellum. Louis Pasteur bewees in 1864 dat deze bacterie de oorzaak was van de omzetting van ethanol naar azijnzuur. Het is een goedaardig micro-organisme dat alom aanwezig is in het milieu, in alcoholbevattende ecologische niches, bloemen, vruchten, bijen, alsook in water en bodems. De bacterie leeft waar fermentatie van suikers optreedt en groeit het best bij temperaturen tussen 25 en 30°C en een pH-waarde die varieert tussen 5,4 en 6,3. De bacterie wordt al sinds lange tijd gebruikt in de fermentatie-industrie om azijnzuur te produceren uit alcohol. Acetobacter aceti is obl

For a long time it has been used in the fermentation industry to produce acetic acid from alcohol. Acetobacter aceti is an obligate aerobe, which means that it requires oxygen to grow. Acetobacter aceti is economically important because it is used in the production of vinegar by converting the ethanol in wine or cider into acetic acid. The acetic acid created by A. aceti is also used in the manufacturing of acetate rayon, plastics production, rubber production, and photographic chemicals. A. aceti is considered an acidophile, which means it is able to survive in acidic environments, due to having an acidified cytoplasm which makes nearly all proteins in the genome to evolve acid stability. A. aceti has become important in helping to understand the process by which proteins can attain acid stability.
