Fermentation is a process used to produce wine, beer, yogurt and other products. Here's a look at the chemical process that occurs during fermentation.
Key Takeaways: Fermentation
Fermentation is a biochemical reaction that extracts energy from carbohydrates without using oxygen.
Organisms use fermentation to live, plus it has many commercial applications.
Possible fermentation products include ethanol, hydrogen gas, and lactic acid.
Fermentation Definition
Fermentation is a metabolic process in which an organism converts a carbohydrate, such as starch or a sugar, into an alcohol or an acid. For example, yeast performs fermentation to obtain energy by converting sugar into alcohol. Bacteria perform fermentation, converting carbohydrates into lactic acid. The study of fermentation is called zymology.
History of Fermentation
The term "ferment" comes from the Latin word fervere, which means "to boil." Fermentation was described by late 14th century alchemists, but not in the modern sense. The chemical process of fermentation became a subject of scientific investigation about the year 1600.

Fermentation is a natural process. People applied fermentation to make products such as wine, mead, cheese, and beer long before the biochemical process was understood. In the 1850s and 1860s, Louis Pasteur became the first zymurgist or scientist to study fermentation when he demonstrated fermentation was caused by living cells. However, Pasteur was unsuccessful in his attempts to extract the enzyme responsible for fermentation from yeast cells. In 1897, German chemist Eduard Buechner ground yeast, extracted fluid from them, and found the liquid could ferment a sugar solution. Buechner's experiment is considered the beginning of the science of biochemistry, earning him the 1907 Nobel Prize in chemistry.
Examples of Products Formed by Fermentation
Most people are aware of food and beverages that are fermentation products, but may not realize many important industrial products results from fermentation.
Beer
Wine
Yogurt
Cheese
Certain sour foods containing lactic acid, including sauerkraut, kimchi, and pepperoni
Bread leavening by yeast
Sewage treatment
Some industrial alcohol production, such as for biofuels
Hydrogen gas
