In a simple stirred-tank bioreactor, what is the primary function of its cylindrical shape or curved base?
Options
- ATo drastically increase the oxygen transfer area via sterile air bubbles
- BTo facilitate the even mixing of the reactor contents
- CTo regulate the temperature and pH of the culture medium
- DTo control and break down foam during the fermentation process
Correct answer
B. To facilitate the even mixing of the reactor contents
Step-by-step solution
A stirred-tank reactor is usually cylindrical or with a curved base to facilitate the mixing of the reactor contents. The stirrer facilitates even mixing and oxygen availability throughout the bioreactor.
Other components like the sparger increase the oxygen transfer area, the foam breaker controls foam, and specific control systems regulate temperature and pH.
Answer: To facilitate the even mixing of the reactor contents
