acetic acid fermentation process

PDF	Acetic Acid Production Acetic acid (CH3COOH) is also called as vinegar • Vinegar fermentation is one of the oldest fermentations known to man

What are the methods of producing acetic acid?
Acetic acid is produced industrially both synthetically and by bacterial fermentation.
About 75% of acetic acid made for use in the chemical industry is made by the carbonylation of methanol, explained below.
Acetic acid is mainly produced via chemical route which involves homogeneous as well as heterogeneous catalytic methods.
The carbonylation of methanol via Monsanto process is the most adapted route, which further evolved as Cavita process with a choice of catalysts and process intensification.

What is the end product of acetic acid fermentation?

At the end of fermentation, the main products are ethanol, lactic acid, acetic acid and other metabolites, such as mannitol, glycerol, esters, aldehydes and other organic acids (78, 79).

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).
