Results for “what is fermentation” · retrieved September 22, 2026
Fermentation is an anaerobic metabolic process that breaks down organic compounds to produce energy and various byproducts like alcohol or acids.
Biochemically, fermentation is an anaerobic metabolic process where organisms break down organic compounds, such as glucose, to generate energy in the form of ATP. This enzyme-catalyzed process involves transferring electrons to organic molecules rather than oxygen. In industrial and culinary contexts, it refers to the use of microorganisms like bacteria, yeast, or molds to transform organic substances into products such as alcohol, acids, or biomass. While often associated with the absence of air, food fermentation can occur in both aerobic and anaerobic conditions.
Answer details
Anaerobic Energy Production
It is an anaerobic process, meaning it does not require oxygen to extract energy from carbohydrates like sugar.
Microbial Transformation
Microorganisms such as yeast and bacteria are used to convert organic substances into useful products like ethanol, lactic acid, and carbon dioxide.
Industrial and Culinary Uses
It is widely used in industries to produce food, beverages, pharmaceuticals, and biofuels by controlling microbial enzymatic activity.
Food Fermentation Context
In food production, fermentation can occur with or without oxygen and creates metabolites that influence a food's flavor, texture, and nutritional profile.

About this answerFermentation | Definition, Process, & Facts
What is fermentation?...Fermentation is a chemical process where molecules like glucose are broken down without oxygen. This process, used for millennia in making wine and beer, creates frothing from carbon dioxide release. Louis Pasteur defined fermentation as changes from yeasts and microbes growing without air, noting that ethyl alcohol and carbon dioxide aren't the only results....Today, fermentation means the enzyme-driven, energy-releasing

Fermentation
Fermentation is a type of anaerobic metabolism that harnesses the redox potential of the reactants to make adenosine triphosphate (ATP) and organic end products. [1] [2] Organic molecules, such as glucose or other sugars, are catabolized and their electrons are transferred to other organic molecules (cofactors, coenzymes, etc.). [1] Anaerobic glycolysis is a related term used to describe the occurrence of fermentation in organisms (usually multic

FERMENTATION Definition & Meaning - Merriam-Webster
: the enzyme-catalyzed anaerobic breakdown of an energy-rich compound (such as a carbohydrate to carbon dioxide and alcohol or to an organic acid) by the action of microorganisms (such as bacteria or yeast) that occurs naturally and is commonly used in the production of various products (such as food, alcoholic beverages, and pharmaceuticals) especially by controlling microbial enzymatic activity...broadly : any of various enzyme-catalyzed aerobi
