Fermentation – What is it? Fermentation is a biological process in which microorganisms, such as bacteria or yeasts, break down specific nutrients and produce metabolic products. Unlike decay or putrefaction, fermentation does not involve degradation in the presence of oxygen. Types of fermentation There are different types of fermentation, which can be distinguished by the microorganisms and substrates involved. The best-known types are alcoholic fermentation, lactic acid fermentation and acetic acid fermentation. Alcoholic fermentation is used, for example, in the production of wine and beer. Yeasts decompose sugars to ethanol and carbon dioxide. Lactic acid fermentation occurs, for example, in the production of sauerkraut or yogurt. In this process, carbohydrates are broken down by lactic acid bacteria. Acetic acid fermentation is used in the production of vinegar. Alcohol is oxidized to acetic acid by acetic acid bacteria. Advantages of fermentation Fermentation offers several advantages. For example, the fermentation process can extend the shelf life of food because acid formation inhibits spoilage. In addition, fermentation can generate certain nutrients, such as vitamins or amino acids. Fermentation is also used in industry to produce, for example, biofuels or enzymes. Conclusion Fermentation is an important biological process applied in the food industry, medicine and biotechnology. Through fermentation, nutrients can be broken down and transformed, which provides multiple benefits.
