Acetobacter aceti (A. aceti) is a Gram-negative, acidophilic bacterium that is used for the industrial production of acetic acid from ethanol. Oxidation of ethanol by membrane-bound oxidoreductases provides energy for A. aceti and the production of high concentrations of acetic acid is an effective defense mechanism. Acetic acid diffuses through cell membranes at low pH and effectively kills many bacteria, including E. coli, at low millimolar concentrations. The ability of A. aceti to thrive in molar concentrations of acetic acid is partially due to the twin subjects of this thesis, the acetic acid resistance factors AarA (citrate synthase, …
