This is a complex chemical reaction whereby the yeast interacts with the sugars (glucose and fructose) in the must, to create ethanol and carbon dioxide. Carefully selected strains of yeasts, bacteria, and molds are used. where a sugar ( glucose) solution containing yeast. Alcoholic fermentation is possibly the most well known of the three types, its byproducts having been enjoyed by human civilization for millennia. Fermentation occurs in yeast cells and bacteria and also in the muscles of animals. Fermentation has been used in food production for millennia. These living things create substances called enzymes. 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. At its simplest, biotechnology is technology based on biology - biotechnology harnesses cellular and biomolecular processes to develop technologies and products that help improve our lives and the health of our planet.

In the presence of carbon dioxide: an anaerobic breakdown of carbohydrates and other organic compounds to form alcohol and organic acids How Beer Works. Fermentation is the process by which yeast converts the glucose in the wort to ethyl alcohol and carbon dioxide gas -- giving the beer both its alcohol content and its carbonation. To begin the fermentation process, the cooled wort is transferred into a fermentation vessel to which the yeast has already been added. Process of Fermentation. One way to investigate fermentation is to study the production of carbon dioxide under different conditions. Normal human colonic pH values are between pH 5.5 and 7.5. Fermentation is also used more broadly to refer to the bulk growth of fermentation, process by which the living cell is able to obtain energy through the breakdown of glucose and other simple sugar molecules without requiring oxygen.
