Triple Science – The Fermentation Process

Explore the science of ethanol and its production through fermentation, a crucial biological process. Ethanol, also known as ethyl alcohol, is an organic compound produced by the fermentation of sugars by yeasts and bacteria in anaerobic conditions. This process is invaluable in creating a variety of products, including alcoholic beverages, bread, yogurt, cheese, and soy sauce. Learn about the breakdown of glucose, the role of enzymes, and how fractional distillation enhances ethanol purity. Dive into the diverse applications of ethanol in our daily lives and its potential as a cleaner fuel additive.

  1. Triple Science – The Fermentation Process By Arran Gill

  2. What is Ethanol? • Ethyl alcohol, ethanol, fermentation alcohol, grain alcohol (the intoxicating agent in fermented and distilled liquors; used pure or denatured as a solvent or in medicines and colognes and cleaning solutions and rocket fuel; proposed as a renewable clean-burning additive to gasoline) ethyl alcohol, ethanol, fermentation alcohol, grain alcohol (the intoxicating agent in fermented and distilled liquors; used pure or denatured as a solvent or in medicines and colognes and cleaning solutions and rocket fuel; proposed as a renewable clean-burning additive to gasoline)

  3. Ethanol Fermentation • Breakdown of sugars by bacteria and yeasts using a method of respiration without oxygen (anaerobic). The enzymes in yeast break down glucose to give two products: ethanol (alcohol) and carbon dioxide. Fermentation processes have long been utilized in baking bread, making beer and wine, and producing cheese, yogurt, soy sauce, and many other foodstuffs. C6H12O6 → 2C2H5OH + 2CO2 • The ethanol solution can be concentrated by fractional distillation to make products like whisky and brandy. Ethanol boils at 78 degrees celsius, so when an ethanol-water mixture is heated, the ethanol boils at a lower temperature and is separated. The liquid distils over at 78 degrees celcius is 96% pure ethanol.
