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. It also takes place in some species of fish where it provides energy when oxygen is scarce. Ethanol fermentation has many uses, including the production of al
Most of the ethanol used in industry is made, not by alcoholic fermentation, but by an addition reaction between ethene and steam. Alcoholic Fermentation. Whatever method of preparation is used, the ethanol is initially obtained in admixture with water.he ethanol is then extracted from this solution by fractional distillation. Ethanol is a colourless liquid with a pleasant smell. It is completely miscible with water and organic solvents and is very hydroscopic. Ethanol is used. 1  A solution of sucrose, to which yeast is added, is heated.
