and (E). 
- Steam for sterilization, (E) - Acid/base for pH control - Acid/Base for pH control, (E) – Motor - Sterile air, (E) - Steam for sterilization - Motor, (E) - Acid/base for pH control
- Steam for sterilization, (E) - Acid/base for pH control - Acid/Base for pH control, (E) – Motor - Sterile air, (E) - Steam for sterilization - Motor, (E) - Acid/base for pH control
Text Solution
Verified by ExpertsThe correct answer is:
A
Looking at the stirred-tank bioreactor diagram, the parts can be identified as follows:
→ Motor (drives the impeller for mixing)
→ Foam breaker (prevents excessive foam formation)
→ Sterile air (for aeration)
→ Steam for sterilization (sterilizes the vessel before culture)
(E) → Acid/base for pH control (maintains optimal pH during fermentation).
