Mikrobifermantaatio, or microbial fermentation, is a metabolic process that converts sugars into acids, gases, or alcohol. It occurs in yeast and bacteria, and also in oxygen-starved muscle cells, as in the case of lactic acid fermentation. This process is ancient and has been harnessed by humans for millennia to produce a variety of foods and beverages.

The fundamental principle of fermentation involves microorganisms, such as bacteria or yeast, breaking down carbohydrates like sugars in the absence of oxygen. Different microorganisms produce different end products. For example, yeast produces ethanol and carbon dioxide during alcoholic fermentation, which is key to making bread and alcoholic drinks like beer and wine. Lactic acid bacteria, on the other hand, produce lactic acid, a process vital for making yogurt, sauerkraut, and kimchi.

Beyond food production, microbial fermentation plays crucial roles in various industries. It is used in the pharmaceutical industry for producing antibiotics and other drugs, and in biotechnology for creating biofuels and enzymes. The controlled application of microbial fermentation allows for the preservation of food, enhances digestibility, and can even create novel flavors and textures. Understanding the specific microorganisms and conditions required is essential for successful fermentation.
