Definition: Fermentation is the chemical transformation of organic substances into simpler compounds by the action of enzymes, complex organic catalysts, which are produced by microorganisms such as molds, yeasts, or bacteria. A substrate is oxidised and an electron carriers (NAD(P)+ or FAD) are reduced, then substrate (typically a derivative of the starting substrate) is reduced. Fermentation is the process whereby “sugars” are converted by yeast to alcohol, carbon dioxide, and heat. cells. The use of fermentation to make bread rise can be traced to the Egyptians in 3000 BC. alcoholic fermentation . Products excreted from cell may be used as energy or carbon sources by others.

Wei-Cho Huang, I-Ching Tang, in Bioprocessing for Value-Added Products from Renewable Resources, 2007. In biochemistry, it is narrowly defined as the extraction of energy from carbohydrates in the absence of oxygen. Fermentation is the process of producing ATP in the absence of oxygen, through glycolysis alone. 1. the production of energy in the absence of oxygen, NADH is converted back to NAD+ by adding the extra electrons in NADH to an organic molecule that acts as an electron acceptor, What are the 2 fermentation pathways eukaryotic cells use to change NADH to NAD+. The pyruvate from glycolysis[10] undergoes a simple redox reaction, forming lactic acid. If air is present, the oxygen causes the ethanol to oxidise to ethanoic acid, so the drink tastes of vinegar.
