However, it may also take place in higher organisms under certain conditions. What Are the Two Main Types of Fermentation? When cows eat this plant, it is concentrated in the milk they produce. In alcoholic fermentation, pyruvic acid, an intermediate molecule, is converted into ethanol with the release of carbon dioxide. The production of particular types of gas is used as an indicator of the fermentation of specific carbohydrates, which plays a role in the laboratory identification of the bacteria. Fermentation is of different types and takes place under anaerobic conditions mostly in saprophytic microorganisms like certain bacteria and fungi. Alcoholic or ethanol fermentation is the process in which the sugars glucose, fructose and sucrose in food is converted to energy. The chemical reactions of lactic acid fermentation are the following: [latex]\text{Pyruvic acid}+\text{NADH}\longleftrightarrow\text{lactic acid}+\text{NAD}^+[/latex].
