Question

Match List I with List II:

List I		List II
A	Clostridium butylicum	I	Ethanol
B	Saccharomyces cerevisiae	II	Streptokinase
C	Trichoderma polysporum	III	Butyric acid
D	Streptococcus sp.	IV	Cyclosporin-A

Choose the correct answer from the options given below:

• A. A-III, B-I, C-II, D-IV
• B. A-II, B-IV, C-III, D-I
• C. A-III, B-I, C-IV, D-II
• D. A-IV, B-I, C-III, D-II

Answer 1

The Correct Option is C

(A) Clostridium butylicum: Produces butyric acid, a short-chain fatty acid.

(B) Saccharomyces cerevisiae: Utilized in fermentation for ethanol production.

(C) Trichoderma polysporum: Used to produce cyclosporin-A, an immunosuppressant.

(D) Streptococcus sp.: Produces streptokinase, an enzyme for dissolving blood clots.

The accurate matching is:

\[ \begin{array}{|c|c|} \hline \textbf{Microorganism} & \textbf{Product} \\ \hline \textbf{A.} \ Clostridium\ butylicum & \text{Butyric Acid (III)} \\ \textbf{B.} \ Saccharomyces\ cerevisiae & \text{Ethanol (I)} \\ \textbf{C.} \ Trichoderma\ polysporum & \text{Cyclosporin-A (IV)} \\ \textbf{D.} \ Streptococcus\ sp. & \text{Streptokinase (II)} \\ \hline \end{array} \]

Therefore, the correct pairings are:

\[ A \to III, \quad B \to I, \quad C \to IV, \quad D \to II \]

Details:

• Clostridium butylicum yields butyric acid, employed in various biochemical applications.
• Saccharomyces cerevisiae is extensively used in the brewing and baking sectors for ethanol generation through fermentation.
• Trichoderma polysporum synthesizes Cyclosporin-A, a critical immunosuppressant for organ transplantation.
• Streptococcus sp. secretes Streptokinase, an enzyme instrumental in clot-dissolving therapies.

This completes the explanation.
