Question

Match the following pairs:
Trichoderma – Citric Acid
- Polysporum – Statins
- Yeast – Cyclosporin A
- Monascus Purpureus – Ethanol
- Aspergillus Niger – Citric Acid

Hint:

Certain microorganisms are used to produce specific products, such as Aspergillus niger for citric acid and Monascus purpureus for statins.

Answer 1

Step 1: Understanding the products of microorganisms.
- Trichoderma is known to be used in the production of enzymes, but is not directly linked to citric acid production. - Polysporum is involved in the production of statins. - Yeast (e.g., Saccharomyces cerevisiae) is used in the production of cyclosporin A, a drug used for immunosuppression. - Monascus purpureus is used to produce ethanol. - Aspergillus niger is widely used in the production of citric acid, especially in industrial fermentation processes.
Step 2: Conclusion.
The correct matching pairs are: - Trichoderma – (produces enzymes, not citric acid directly) - Polysporum – Statins - Yeast – Cyclosporin A - Monascus Purpureus – Ethanol - Aspergillus Niger – Citric Acid

Answer 2

Step 1: Different microorganisms are used industrially to make different products.

Step 2: Polysporum makes statins, Yeast makes cyclosporin A, Monascus purpureus makes ethanol, and Aspergillus niger makes citric acid.

Step 3: Trichoderma is mainly known for producing enzymes, not citric acid.

Step 4: So the correct product-matches are: Polysporum→Statins, Yeast→Cyclosporin A, Monascus purpureus→Ethanol, Aspergillus niger→Citric Acid.

Answer 3

Matching each organism to its known industrial product:

Trichoderma	Cellulase enzymes (not citric acid)
Polysporum	Statins
Yeast	Cyclosporin A
Monascus purpureus	Ethanol
Aspergillus niger	Citric acid

Going organism by organism this way confirms that citric acid, the product mentioned for Trichoderma in the pairs above, truly belongs to Aspergillus niger, since Trichoderma is instead valued for its cellulase/protease enzymes used in biocontrol and industry.
