Which is a commercial use for lactic acid fermentation? . a. brewing beer. b. baking. c. making wine. d. making cheese

A commercial use for lactic acid fermentation is .

Further Explanation:

Lactic acid is an organic acid that has the molecular formula of . It is obtained from both natural as well as artificial means. It is a type of alpha-hydroxy acid because a carboxyl group is present at an adjacent position to the hydroxyl group. It has wide applications in biochemical and organic synthesis industries, pharmaceutical technology, cosmetics, and forgery.

Lactic acid fermentation is a method to convert glucose or sugars containing six carbons into cellular energy and lactate. Lactate is the conjugate base of lactic acid. It forms lactic acid in solution. This fermentation is carried out without oxygen and is therefore called anaerobic fermentation. It occurs in some animal cells and bacteria.

Wine is produced by the process called winemaking or vinification. This involves a series of steps. Firstly, harvesting or picking of fruits (grapes) is done. These fruits are then taken to the winery where these are prepared for primary ferment. This technique is different for red and white wines. After this stage, the free run wine is put into tanks and the residual juice and wine are extracted. The remaining sugars are converted into alcohol and carbon dioxide by keeping the wine warm. The wine is allowed to settle before pouring it into bottles. The steps for wine formation may vary depending on the quality of the fruits and style of the wine.

Therefore lactic acid fermentation is used in making wine.
