Specifically the process of fermentation refers to the conversion of sugar into alcohol by the use of yeast or use of bacteria in creating lactic acid in certain foods under the right conditions, the process of fermentation occurs naturally in many foods. Yeast is a living bacteria commonly used in baking that makes dough rise through the process of fermentation for fermentation to occur yeast requires fuel in the form of sugar.
