Question:
Monascus purpureus is a yeast used commercially in the production of which one of the following?
Monascus purpureus is a yeast used commercially in the production of which one of the following?
Show Hint
Keep a handy table of industrial microbes:
- Monascus $\rightarrow$ Statins (Cholesterol lowerer)
- Trichoderma $\rightarrow$ Cyclosporin A (Immunosuppressant)
- Streptococcus $\rightarrow$ Streptokinase (Clot buster)
Updated On: Aug 16, 2026
- Ethanol
- Streptokinase
- Citric acid
- Statins
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Microbes play an indispensable role in industrial biotechnology for producing specialized bioactive molecules:
• Saccharomyces cerevisiae (Yeast) $\rightarrow$ Used for fermenting sugars into Ethanol.
• Streptococcus (Bacteria) $\rightarrow$ Genetically engineered to produce Streptokinase (clot buster).
• Aspergillus niger (Fungus) $\rightarrow$ Commercially utilized for Citric acid production.
• Monascus purpureus (Yeast) $\rightarrow$ Industrially cultivated to synthesize Statins.
Step 1: Match the specific organism to its product.
The organism listed is Monascus purpureus, a species of mold-like yeast.
Step 2: Determine the physiological action of its product.
Monascus purpureus naturally produces statins. Statins act as potent blood-cholesterol lowering agents. They achieve this therapeutic effect by acting as competitive inhibitors of the enzyme responsible for endogenous cholesterol synthesis (HMG-CoA reductase).
Step 3: Confirm selection against choices.
Reviewing the options confirms that Statins is Option (D).
