Alcoholic Fermentation – Energy Balance (2) The contact with oxygen is another crucial factor. Even a small amount of oxygen can completely stop the fermentation process, in what is known as the Pasteur effect. That’s why it’s important to keep the fermentation containers well sealed, no air!And last but not least, the growth rate of …
Alcoholic Fermentation – Energy Balance Imagine a process that occurs in darkness, without oxygen, and releases energy in the form of molecules called ATP. That’s alcoholic fermentation! Yeast cells, those tiny unicellular wonders, carry out this process to obtain the energy they need to perform their metabolic functions, such as growing and reproducing.The most surprising …
Alcoholic Fermentation – Biochemistry of the Reaction Alcoholic fermentation is a biochemical process in which sugar molecules are broken down into ethanol and carbon dioxide with the help of enzymes. This chemical reaction occurs during glycolysis, which is the metabolic pathway that allows sugar to enter fermentation. Ethanol and carbon dioxide are waste products of …

Alcoholic Fermentation – Yeasts (2) When the sugar content in the medium is high, as in the case of syrups or molasses, yeast survival is affected during the process of converting sugar to alcohol due to the sugar concentration, usually measured in degrees Brix. High sugar concentrations slow down the osmotic processes of cell membranes, …
Alcoholic Fermentation – Yeasts Yeasts, which usually have a round shape and a size of between 2 and 4 μm, can be found naturally in certain foods such as fruits, cereals, and vegetables. These organisms are known as facultative anaerobes, which means they can function without oxygen.Microscopic fungi, including species such as Saccharomyces cerevisiae, Kluyveromyces …
