Ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products. During this time bacteria converts sugar of product in lactic acid and so product gets its sour taste. Beer, wine, yogurt, pickled food, cheese, and bread are produced as a result of fermentation of food items. Fuel sources used at present are non-renewable and sure enough, will not that readily available in future if we keep them exploiting like this. The function of these bacteria is to convert lactose sugar of milk into lactic acid, and so yogurt gets its specific flavor. Possible fermentation products include ethanol, hydrogen gas, and lactic acid. For the preparation of fermented products, a unique mixture is required that contain microorganisms and other components. Fermentation w [von latein. Yogurt is a dairy product of creamy consistency, of remarkable viscosity, generated through the fermentation of milk, which usually comes from cattle. Fermentation recycles NAD +, and produces 2 ATPs. The process of fermentation was used in making beverages such as beer and wine, since as early as the year 7000 BC.
