The chemical compound produced as a byproduct of fermentation is primarily ethanol or alcohol. Fermentation is an anaerobic process where microorganisms convert sugars into energy, leading to the production of ethanol and carbon dioxide. This process is essential in various applications, including the production of alcoholic beverages, bread, and biofuels. In addition to ethanol, other byproducts may include organic acids, gases, and secondary metabolites,depending on the organism and conditions. Fermentation has significant industrial and ecological importance.
