Species of bacterium

Acetobacter aceti, a Gram-negative bacterium that moves using its peritrichous flagella, was discovered when Louis Pasteur proved it to be the cause of conversion of ethanol to acetic acid in 1864. Today, A. aceti is recognized as a species within the genus Acetobacter, belonging to the family Acetobacteraceae in the class Alphaproteobacteria.[1] Its bacterial motility plays an important role in the formation of biofilms, intricate communities where A. aceti cells aggregate and collaborate, further enhancing their ability to metabolize ethanol and produce acetic acid.[2] Widely distributed in various environmental niches, this benign microorganism thrives in habitats abundant in fermentable sugars, such as flowers, fruits, honey, water, and soil, present wherever sugar fermentation occurs.[3]A. aceti grows best within temperatures ranging from 25 to 30 degrees Celsius, with an upper limit of 35 degrees Celsius, and in slightly acidic conditions with a pH...
