A
anaerobic

Explanation: 

Detailed explanation-1: -Answer and Explanation: The products of fermentation depend on the type of organism carrying out the process. Yeasts are used to produce e. wine, beer, and bread with alcohol fermentation.

Detailed explanation-2: -In lactic acid fermentation, pyruvate from glycolysis changes to lactic acid. This type of fermentation is carried out by the bacteria in yogurt, and by your own muscle cells. In alcoholic fermentation, pyruvate changes to alcohol and carbon dioxide. This type of fermentation is carried out by yeasts and some bacteria.

Detailed explanation-3: -It produces carbon dioxide and lactic and acetic acids, which quickly lower the pH, thereby inhibiting development of undesirable microorganisms that might destroy crispness. The carbon dioxide produced replaces the air and facilitates the anaerobiosis required for the fermentation.
