Match List-I with List-II
| List-I | List-II |
|---|---|
| Product | Producer |
| (A) Citric Acid | (I) Trichoderma polysporum |
| (B) Ethanol | (II) Monascus purpureus |
| (C) Statins | (III) Saccharomyces cerevisiae |
| (D) Cyclosporin A | (IV) Aspergillus niger |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → (A) - (IV), (B) - (III), (C) - (II), (D) - (I)
(A) Citric Acid — this matches (IV) Aspergillus niger. This fungus is used to make citric acid on a large scale.
(B) Ethanol — this matches (III) Saccharomyces cerevisiae. Brewer’s yeast ferments sugars to ethanol. It is used to make beer, wine and industrial alcohol.
(C) Statins — this matches (II) Monascus purpureus. This yeast makes statins, which lower blood cholesterol by blocking the enzyme that makes it.
(D) Cyclosporin A — this matches (I) Trichoderma polysporum. This fungus makes cyclosporin A, an immunosuppressive agent given to organ-transplant patients.

NCERT Extract:
Chemicals, Enzymes and other Bioactive Molecules – “Microbes are also used for commercial and industrial production of certain chemicals like organic acids, alcohols and enzymes. Examples of acid producers are Aspergillus niger (a fungus) of citric acid, Acetobacter aceti (a bacterium) of acetic acid; Clostridium butylicum (a bacterium) of butyric acid and Lactobacillus (a bacterium) of lactic acid. … Another bioactive molecule, cyclosporin A, that is used as an immunosuppressive agent in organ-transplant patients, is produced by the fungus Trichoderma polysporum. Statins produced by the yeast Monascus purpureus have been commercialised as blood-cholesterol lowering agents.”
