Question

A bioreactor working for industrial production of antibiotics must maintain maximum microbial growth and product formation. Match the following components with their correct functions. 

Component	Function
(P) Sparger	(1) Uniform oxygen distribution
(Q) Agitator	(2) Uniform mixing of nutrients
(R) Cooling Jacket	(3) Removal of excess metabolic heat
(S) Foam Breaker	(4) Prevention of foam accumulation

Choose the correct option.

• A. \(P \rightarrow 1,\ Q \rightarrow 2,\ R \rightarrow 3,\ S \rightarrow 4\)
• B. \(P \rightarrow 2,\ Q \rightarrow 1,\ R \rightarrow 4,\ S \rightarrow 3\)
• C. \(P \rightarrow 3,\ Q \rightarrow 2,\ R \rightarrow 1,\ S \rightarrow 4\)
• D. \(P \rightarrow 1,\ Q \rightarrow 4,\ R \rightarrow 2,\ S \rightarrow 3\)

Hint:

Important bioreactor parts:
• Sparger \(\rightarrow\) aeration
• Agitator \(\rightarrow\) mixing
• Cooling jacket \(\rightarrow\) temperature control
• Foam breaker \(\rightarrow\) foam prevention

Answer 1

The Correct Option is A

Concept: Bioreactors are large vessels used for industrial-scale production of useful biological products. Efficient microbial growth requires:
• oxygen supply
• proper mixing
• heat regulation
• foam control

Step 1: Understanding sparger function. Sparger introduces sterile air bubbles into the medium. Its primary function is: \[ \text{uniform oxygen distribution} \] Thus: \[ P \rightarrow 1 \]

Step 2: Understanding agitator function. Agitator rotates continuously and ensures:
• proper mixing
• nutrient distribution
• homogeneous conditions Thus: \[ Q \rightarrow 2 \]

Step 3: Understanding cooling jacket function. Microbial metabolism generates large amounts of heat. Cooling jacket helps in: \[ \text{removal of excess heat} \] Thus: \[ R \rightarrow 3 \]

Step 4: Understanding foam breaker function. Foam formation may:
• reduce efficiency
• contaminate cultures Foam breaker prevents foam accumulation. Thus: \[ S \rightarrow 4 \] Final matching: \[ P \rightarrow 1,\quad Q \rightarrow 2,\quad R \rightarrow 3,\quad S \rightarrow 4 \] Hence correct option is (A). Final Answer: \[ \boxed{(A)} \]
