Which fermentation product is primarily associated with lactose fermentation?

• A. Carbon dioxide
• B. Alcohol
• C. Lactic acid
• D. Hydrogen gas

Answer: (C)

The fermentation product primarily associated with lactose fermentation is lactic acid. This process occurs when lactose, a sugar found in milk, is broken down by lactic acid bacteria, which are capable of fermenting lactose. During this anaerobic process, the bacteria convert lactose into lactic acid, along with a small amount of energy. Lactic acid fermentation is especially important in food production, as it contributes to the sour taste of yogurt and other dairy products. The production of lactic acid lowers the pH of the environment, which helps inhibit the growth of unwanted bacteria and preserves the food. While carbon dioxide, alcohol, and hydrogen gas can be produced through other types of fermentation (such as alcoholic fermentation or various types of anaerobic fermentation), they are not the main products generated from lactose fermentation specifically. This makes lactic acid the defining product in this context, highlighting the role of lactic acid bacteria in food science and microbiology.
