A metabolic process called fermentation turns sugar or starch into alcohol or organic acids. It is employed in the production of several goods, like as beer, wine, bread, yoghurt, and cheese. Additionally, fermentation can be utilized to remediate garbage and make biofuels. Microorganisms like yeast and bacteria are needed for the process because they eat the sugar or starch and create the required result. Fermentation is a biological process that involves the conversion of carbohydrates by microorganisms such as yeast and bacteria into organic acids, gases, or alcohol. For thousands of years, this method has been used to generate food and beverages such as beer, wine, bread, and yoghurt. Fermentation is also employed in the creation of numerous pharmaceuticals, biofuels, and industrial chemicals in modern times.
