Isolation and identification of the genera Acetobacter and ... 1994). Of these, Gluconobacter oxydans, Acetobacter aceti, Acetobacter pasteurianus, Acetobacter liquefaciens and Acetobacter hansenii are normally associated with grapes and wines (Blackwood et al., 1969; Joyeux et al., 1984a). However, according to Ruiz et al. (2000), acetic acid bacteria are divided into the genera Acetobacter, Acetobacter aceti - Wikipedia 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.
