Question

Match List-I with List-II:

List-I Products	List-II Organisms
(A) Statin	(III) Monascus
(B) Clot buster	(I) Streptococcus
(C) Swiss cheese	(IV) Propionibacterium
(D) Cyclosporin-A	(II) Trichoderma

Choose the correct answer from the options given below:

• (A) - (II), (B) - (I), (C) - (IV), (D) - (III)
• (A) - (III), (B) - (I), (C) - (IV), (D) - (II)
• (A) - (III), (B) - (IV), (C) - (II), (D) - (I)
• (A) - (II), (B) - (III), (C) - (I), (D) - (IV)

Answer 1

The Correct Option is B

The task is to match products listed in List-I with the corresponding organisms in List-II.

List-I Products	List-II Organisms
(A) Statin	(III) Monascus
(B) Clot buster	(I) Streptococcus
(C) Swiss cheese	(IV) Propionibacterium
(D) Cyclosporin-A	(II) Trichoderma

Explanation for the correct matches:

• Statin: Statins are a category of drugs that lower cholesterol levels, primarily produced by the fungus Monascus.
• Clot buster: Streptokinase, known as a clot buster, is an enzyme that can break down blood clots and is derived from the bacterium Streptococcus.
• Swiss cheese: Known for its characteristic holes and flavor, it is produced using the bacterium Propionibacterium which contributes to these features.
• Cyclosporin-A: This is an immunosuppressant drug, commonly sourced from the fungus Trichoderma.

The correct matches according to the given lists are: (A) - (III), (B) - (I), (C) - (IV), (D) - (II).

Answer 2

Microbial Products and Their Sources 

This question lists several industrially important microbial products and the microorganisms from which they are derived.

1. Statin is produced by Monascus purpureus.

Explanation: Statins are a class of drugs used to lower cholesterol levels in the blood. Monascus purpureus is a type of red yeast that naturally produces statins.

1. Clot busters (Streptokinase) are produced by Streptococcus.

Explanation: Streptokinase is an enzyme that can dissolve blood clots and is used to treat conditions such as heart attacks and pulmonary embolism.

1. Swiss cheese is made using Propionibacterium.

Explanation: Propionibacterium freudenreichii ferments lactic acid, producing propionic acid, acetic acid, and carbon dioxide. The carbon dioxide forms the characteristic "eyes" in Swiss cheese, and the other products contribute to its flavor.

1. Cyclosporin A is an immunosuppressant derived from Trichoderma polysporum.

Explanation: Cyclosporin A is used to suppress the immune system, especially in transplant patients to prevent organ rejection.
