Question

What is the advantage of immobilisation of enzymes and whole cell for industrial production of products?

• A. Improved stability, better efficiency of enzymes and recovery of enzyme at the end of reaction for repeated use
• B. The enzymes require special expensive conditions and cannot carry out reactions at low temperature and low atmospheric pressure
• C. It results in many side-products from which desired product is to be purified
• D. No possibility of manipulation of catalytic reactions

Hint:

Immobilised enzymes: stable, reusable, easily separated from product --- major advantages over free enzymes in industrial bioprocessing.

Answer 1

The Correct Option is A

Step 1: Concept
Enzyme immobilisation technology.

Step 2: Meaning
Immobilisation attaches enzymes or whole cells to a solid support, allowing them to function repeatedly and be easily separated from the product.

Step 3: Analysis
The advantages of enzyme immobilisation include: (i) improved thermal and operational stability; (ii) ease of separation from the product stream; (iii) ability to reuse the enzyme multiple times, reducing cost. Options (B), (C), and (D) describe disadvantages or incorrect statements.

Step 4: Conclusion
Option (A) correctly identifies the key advantages of enzyme immobilisation. Final Answer: (A)
