| List-I | List-II |
|---|---|
| Applications | Microorganisms |
| (A) Immunosuppressive agent | (I) Propionibacterium sharmanii |
| (B) Blood-cholesterol lowering agents | (II) Trichoderma polysporum |
| (C) Nitrogen fixation | (III) Monascus purpureus |
| (D) Holes in ‘Swiss cheese’ | (IV) Oscillatoria |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (A) - (II), (B) - (III), (C) - (IV), (D) - (I)
(A) Immunosuppressive agent — this matches (II) Trichoderma polysporum. This fungus makes cyclosporin A. It is given to organ transplant patients to keep the body from rejecting the new organ.
(B) Blood-cholesterol lowering agents — this matches (III) Monascus purpureus. This yeast makes statins. Statins block the enzyme that makes cholesterol.
(C) Nitrogen fixation — this matches (IV) Oscillatoria. It is a cyanobacterium. Many cyanobacteria fix atmospheric nitrogen and are used as biofertilisers, for example Anabaena, Nostoc and Oscillatoria.
(D) Holes in ‘Swiss cheese’ — this matches (I) Propionibacterium sharmanii. This bacterium makes a large amount of carbon dioxide, and the gas forms the holes.
