[PDF] acetic acid fermentation process

To produce acetic acid, we need to follow two processes: We must use the yeast that converts glucose or sugar to alcohol. We use acetobacter and other bacteria to convert ethyl alcohol to acetic acid. To oxidise ethanol to acetic acid, a massive amount of oxygen comes to need.

  • What are the steps in acetic acid fermentation?

    This product is the result of a two-stage fermentation. The first step is an anaerobic fermentation (alcoholic fermentation of sugars into ethanol by yeasts) and the second step is an aerobic fermentation (oxidation of ethanol into acetic acid by AAB).

  • What is the process of acetic acid fermentation in vinegar?

    Fermentation of Alcohol Into Vinegar
    In the presence of oxygen, acetic acid bacteria convert the alcohol into acetic acid, also known as vinegar. This process is called acetic fermentation. Once the vinegar has properly fermented, it can be aged. Young vinegar is often very aggressive on the palate.
  • Anaerobic fermentation
    Species of anaerobic bacteria, including members of the genus Clostridium or Acetobacterium can convert sugars to acetic acid directly without creating ethanol as an intermediate. The overall chemical reaction conducted by these bacteria may be represented as: C 6H 12O 6 ? 3 CH 3COOH.
