What does AF mean in BIOTECHNOLOGY
Aerobic fermentation (AF) is a metabolic process that occurs in certain microorganisms, such as yeast, under aerobic conditions (in the presence of oxygen). Unlike anaerobic fermentation, which does not require oxygen, AF utilizes oxygen to generate energy.
AF meaning in Biotechnology in Academic & Science
AF mostly used in an acronym Biotechnology in Category Academic & Science that means Aerobic Fermentation
Shorthand: AF,
Full Form: Aerobic Fermentation
For more information of "Aerobic Fermentation", see the section below.
- Aerobic Fermentation (AF) is a process in which microorganisms use oxygen as the final electron acceptor in the fermentation of organic substrates.
AF
- AF is a type of fermentation that occurs in the presence of oxygen.
- It is a metabolic pathway that involves the partial oxidation of organic compounds to produce energy.
- AF is typically associated with the growth of bacteria, fungi, and yeasts, and is used in the production of various industrial products, such as ethanol, lactic acid, and antibiotics.
- The key steps in AF include:
- Glycolysis: Glucose is broken down into pyruvate.
- Pyruvate oxidation: Pyruvate is converted to acetyl-CoA.
- Acetyl-CoA oxidation: Acetyl-CoA is oxidized to CO2 and water.
- Electron transfer: Electrons released during the oxidation of acetyl-CoA are transferred to electron carriers, such as NADH and FADH2.
- Oxidative phosphorylation: Electrons from NADH and FADH2 are transferred to the electron transport chain, which pumps protons across the cell membrane.
- Proton motive force: The proton gradient across the cell membrane is used to generate ATP through ATP synthase.
Essential Questions and Answers on Aerobic Fermentation in "SCIENCE»BIOTECH"
What is Aerobic Fermentation (AF)?
How does AF differ from Anaerobic Fermentation?
In anaerobic fermentation, microorganisms break down glucose in the absence of oxygen, producing byproducts such as ethanol or lactic acid. In contrast, AF occurs in the presence of oxygen, and the main byproducts are carbon dioxide and water. Additionally, AF is more efficient than anaerobic fermentation in terms of energy production.
What are the advantages of AF?
AF offers several advantages, including:
- Higher energy yield compared to anaerobic fermentation
- Production of desired products, such as citric acid and gluconic acid
- Can occur in conditions with varying oxygen availability
Where is AF applied in industry?
AF is widely used in industrial processes, such as:
- Production of citric acid, a common food additive
- Manufacturing of gluconic acid, used in cleaning products
- Production of pharmaceuticals and other biochemicals
What is the role of oxygen in AF?
Oxygen serves as the final electron acceptor in the AF process. By utilizing oxygen, microorganisms can extract more energy from glucose, leading to a higher energy yield.
Final Words:
- AF involves utilizing oxygen as the final electron acceptor in the fermentation process, resulting in the production of energy and various industrial products.
