fermentacion

Fermentation, a type of anaerobic respiration , an energy-releasing process that takes place in the absence of free (chemically uncombined) oxygen. Fermentation results in the breakdown ofcarbohydrates and other complex organic substances into simpler substances.
Certain organisms perform fermentation to obtain the energy they need to carry on their life processes. (Most organisms obtain theenergy for these processes through aerobic respiration, in the presence of free oxygen). Various microorganisms, including yeasts and certain molds and bacteria, obtain their energy throughfermentation. Many of the fermentation processes result in products that are important in medicine, food preparation, and other fields.
The specific product resulting from fermentation is determined by the typeof microorganism the product of yeast fermentation in fruit juice, while beer is the product of yeast fermentation in grain. Antibiotics (drugs used to fight infectious diseases) are obtained fromboth bacterial and mold fermentation. Fermentation by various microorganisms is used to produce substances called enzymes, which are used in many medical and industrial processes to speed up chemicalreactions. Vinegar and cheese are products of bacterial fermentation. Yeast fermentation is used to make leavened bread.
