Match List-I with List-II.
| List-I | List-II |
|---|---|
| Microorganism | Product |
| (A) Saccharomyces cerevisiae | (I) Butyric acid |
| (B) Aspergillus niger | (II) Statins |
| (C) Clostridium butylicum | (III) Citric acid |
| (D) Monascus purpureus | (IV) Ethanol |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → (A)-(IV), (B)-(III), (C)-(I), (D)-(II)
(A) Saccharomyces cerevisiae — this matches (IV) Ethanol. This yeast ferments sugars in the absence of oxygen and gives ethanol. It is used to make alcohol and alcoholic drinks.
(B) Aspergillus niger — this matches (III) Citric acid. This fungus is used in industry to produce citric acid.
(C) Clostridium butylicum — this matches (I) Butyric acid. This bacterium produces butyric acid, as its name suggests.
(D) Monascus purpureus — this matches (II) Statins. This yeast produces statins. Statins lower blood cholesterol by blocking the enzyme that makes cholesterol.
