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
