Fermentation

Fermentation is the process of deriving energy from the oxidation of organic compounds, such as carbohydrates, using an endogenous electron acceptor, which is usually an organic compound [1].



change in an organic substance caused by a ferment, such as souring of milk, with little or no oxygen involved, that is, anaerobic respiration

Alcohol fermentation is the formation of alcohol from sugar. Yeast, when under anaerobic conditions, convert glucose to pyruvic acid via the glycolysis pathways, then go one step farther, converting pyruvic acid into ethanol, a C-2 compound.

There is another way that the NADH molecule can be re-oxidized. Anaerobic conditions in yeast convert pyruvate to carbon dioxide and ethanol.

Fermentation
- A process of growing microorganisms to produce various chemical or pharmaceutical compounds. Microbes are usually incubated under specific conditions in large tanks called fermenters. Fermentation is a specific type of bioprocessing.

(alcoholic) A type of anaerobic respiration that yields carbon dioxide and alcohol; used in commercial processes, including production of raised bakery dough products and alcoholic beverages.

At high D (greater than 0.3/hour), yeast cells switch their metabolism from pure respiration to a mix of fermentation and respiration.

Feedback inhibition Fen-Phen Anaerobic decomposition of an organic compound (e.g., glucose) by a living organism.

ferments are of two kinds: (a) formed or organised ferments. (b) unorganised or structureless ferments. The latter are also called soluble or chemical ferments, and enzymes.

It's a whole process called fermentation. Sugars are broken down in an environment without oxygen. It's called anaerobic fermentation. And voila, alcohol. Even though they are single celled, you may find them in colonies.

Anaerobic respiration (both glycolysis and ) takes place in the fluid portion of the cytoplasm whereas the bulk of the energy yield of aerobic respiration takes place in the mitochondria.
