Fermentation is an anaerobic process in which energy can be released from glucose even though oxygen is not available. Fermentation occurs in yeast cells, and a form of fermentation takes place in bacteria and in the muscle cells of animals. Alcohol fermentation is a complex biotechnological process in which sugars such as glucose, sucrose, and fructose are converted into energy molecules and produce ethanol, carbon dioxide, and metabolic by-products during this process. These products contribute to the sensorial properties and chemical composition of the fermented foodstuff.

Type […] Alcoholic fermentation is the best known of the fermentation processes, and is involved in several important transformation, stabilization, and conservation processes for sugar-rich substrates, such as fruit, and fruit and vegetable juices. Alcoholic fermentation is carried out by yeasts and some other fungi and bacteria. As the fermentation reaction takes place, certain molecules such as proteins, enzymes and fats are produced by the microbe, depending on its genetic makeup. In nature, the microbe undergoes fermentation for its own gain, but us humans can often make use of the substances it produces for our own benefit.

Fermentation biology

Fermentation is a metabolic process that produces chemical changes in organic substrates through the action of enzymes. In biochemistry, it is narrowly defined as the extraction of energy from carbohydrates in the absence of oxygen. In biology, the fermentation process is actually a conversion of sugar into acids or alcohol with the help of bacteria or yeast. The bacteria help in the conversion of sugar into acid, and the yeast is used for the alcohol production.

The ethanol fermentation reaction is shown in Figure 1. In the first reaction, the enzyme pyruvate decarboxylase removes a carboxyl group from pyruvate, releasing CO 2 gas while producing the two-carbon molecule acetaldehyde. Fermentation is another anaerobic (non-oxygen-requiring) pathway for breaking down glucose, one that's performed by many types of organisms and cells. In fermentation, the only energy extraction pathway is glycolysis, with one or two extra reactions tacked on at the end. Fermentation and cellular respiration begin the same way, with glycolysis. Ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products. Because yeasts perform this conversion in the absence of oxygen, alcoholic fermentation is considered an anaerobic process.
