acetic acid fermentation

What is acetate fermentation?
Acetate is found in many fermented foods (e.g., Swiss cheese), and it is an energy source for cattle harboring fermentative microbes (5).
Further, acetate is an often-unwanted by-product in industrial fermentations (e.g., those producing succinate or propionate) (6).
What is the enzyme used in acetic acid fermentation?
Acetobacter uses two membrane-bound enzymes (alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH)) to oxidize ethanol to acetic acid during respiration, after which it further oxidizes acetic acid and lactic acid to carbon dioxide and water._{17 fév. 2021}
How long does acetic fermentation take?
Allow the mixture to ferment until bubbles are readily visible on the surface, about 2 weeks.
Strain the solids from the liquids, and return the vinegar to its warm, dark spot to continue fermenting.
It will pass through a stage of alcoholic fermentation, and then continue on into vinegar.
Building up acidity ? Lactic acid is ten times more acidic than acetic acid.
The Ph is about the free proton concentration, i.e. how many protons are in solution.

The acetic acid fermentation is an extremely exothermic process enhancing the temperature to over 50°C (Peláez et al., 2016). Only a small amount of lactate 2%–4% is converted into acetate by AAB species. Lactate is oxidized by A. pasteurianus via TCA cycle and another part is transformed into acetoin.
