Ethanol Fermentation

‘fermentation refers to any process by which large organic molecules are broken down to simpler molecules as the result of the action of microorganisms’ . The most familiar type of fermentation is the process by which sugars and starches are converted to alcohol by enzymes in yeasts. To distinguish this reaction from other kinds of fermentation, the process is sometimes known as alcoholic or ethanolic fermentation.

Ethanolic fermentation was one of the first chemical reactions observed
by humans .

Equation for ethanol fermentation:
‘A solution of sucrose, to which yeast is added, is heated. An enzyme, invertase, which is present in yeast is added and this acts as a catalyst to convert the sucrose into glucose and fructose.,
