What is the purpose of sampling ports in a bioreactor?

Options

  1. ATo control the temperature
  2. BTo control the pH
  3. CTo withdraw small volumes of culture periodically
  4. DTo control the foam

Correct answer

C. To withdraw small volumes of culture periodically

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. Alternatively air can be bubbled through the reactor. If you look at the figure closely you will see that the bioreactor has an agitator system, an oxygen delivery system and a foam control system, a temperature control system, pH control system and sampling ports so that small volumes of the culture can be withdr
