Sparger in stirred-tank bioreactor primarily provides:
Select the correct option:
Solution
Incorrect! Answer:
Sterile air bubbles
- Bioreactor Design: Large scale production of biological products requires controlled environments. The stirred-tank bioreactor is most common.
- Oxygen Requirement: Aerobic microorganisms need a constant supply of oxygen for growth.
- Aeration System: The sparger is a device (like a perforated pipe) located at the bottom that blows sterile air bubbles into the culture medium.
- Purpose: Bubbles increase the surface area for oxygen transfer from the air to the liquid medium, ensuring cells have enough O2 to metabolize.
