Study Notes

Fermentation is a metabolic process that produces chemical changes in organic substances through the action of enzymes.
It is narrowly defined as the extraction of energy from carbohydrates in the absence of oxygen.
Fermentation is the primary means of producing ATP by the degradation of organic nutrients anaerobically in microorganisms.
Humans have used fermentation to produce foodstuffs and beverages since the Neolithic age.
Fermentation is used for preservation in a process that produces lactic acid found in such sour foods as pickled cucumbers, kombucha, kimchi, and yogurt, as well as for producing alcoholic beverages such as wine and beer.
Fermentation also occurs within the gastrointestinal tracts of all animals, including humans.
Industrial fermentation is a broader term used for the process of applying microbes for the large-scale production of chemicals, biofuels, enzymes, proteins, and pharmaceuticals.
Fermentation normally occurs in an anaerobic environment.
The basic mechanisms for fermentation remain present in all cells of higher organisms.
Fermentation can be used to make alternative protein sources and for enzyme production.
Enzymes are used in various industries such as food, beverage, animal feed, detergents, textile, personal care, and pulp and paper.
Industrial fermentation can be done through batch, fed-batch, open, or continuous procedures.
Batch fermentation is the traditional method and is still used when the process is not well understood.
Fed-batch fermentation allows greater control of the stages of the process and can increase production of secondary metabolites.
Open fermentation approaches can resist contamination and are favored in wastewater treatment.
Continuous fermentation involves adding substrates and removing final products continuously.
Fermentation has been used for thousands of years and has religious significance in some cultures.
Louis Pasteur showed that fermentation is initiated by living organisms and identified the role of microorganisms in food spoilage.
Eduard Buechner discovered that fermentation is caused by enzymes produced by microorganisms.
Advances in microbiology and fermentation technology have continued steadily up until the present.
