Show Hint
Functions of aeration:
\[
\boxed{
\begin{aligned}
&\text{Supply dissolved oxygen}
&\text{Support aerobic microbial growth}
&\text{Enhance product formation}
\end{aligned}
}
\]
Aeration is usually accompanied by agitation to improve oxygen transfer.

- Control temperature
- Provide oxygen for microbial metabolism
- Prevent foaming
- Increase pH
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Recall the role of aeration.
Aeration introduces sterile air into the bioreactor to supply oxygen required by aerobic microorganisms.
Step 2: Identify the primary purpose. Oxygen acts as the terminal electron acceptor during aerobic respiration and is essential for microbial growth and product formation. Hence, \[ \boxed{\text{Provide oxygen for microbial metabolism}} \] is the correct answer. Therefore, \[ \boxed{(B)} \] is the correct answer.
Step 2: Identify the primary purpose. Oxygen acts as the terminal electron acceptor during aerobic respiration and is essential for microbial growth and product formation. Hence, \[ \boxed{\text{Provide oxygen for microbial metabolism}} \] is the correct answer. Therefore, \[ \boxed{(B)} \] is the correct answer.
