Choose the correct option.

Biotechnology : Principles and Processes

Solution:

Large volumes $(100-1000\, L)$ of culture can be processed in bioreactors. A bioreactor provides the optimal conditions for obtaining the desired product. In the sparged stirred-tank bioreactor, sterile air bubbles are sparged. This increases the surface area for oxygen transfer.
