Monascus purpureus is a yeast commerically used in the production of

Options

A. citric acid
B. ethanol
C. blood cholesterol lowering statins
D. streptokinase for removing clots from blood vessels.

Answer

**Step-by-Step Solution:**

1. **Identify the Organism**: The question asks about Monascus purpureus, which is a type of yeast (more accurately, a mold).

2. **Evaluate the Options**: The options given are:
- A) Citric acid
- B) Ethanol
- C) Blood cholesterol-lowering statins
- D) Streptokinase

3. **Analyze Each Option**:
- **Option A: Citric acid**: This compound is primarily produced by the fungus Aspergillus niger, not Monascus purpureus. Therefore, this option is incorrect.
- **Option B: Ethanol**: Ethanol is typically produced by various yeast species, especially Saccharomyces cerevisiae. Monascus purpureus is not known for ethanol production, making this option incorrect as well.
- **Option C: Blood cholesterol-lowering statins**: Monascus purpureus is known for its role in the production of statins, which are used to lower blood cholesterol levels. This option is correct.
- **Option D: Streptokinase**: This is an enzyme produced by Streptococcus species and is used to dissolve blood clots. Monascus purpureus does not produce streptokinase, so this option is incorrect.

4. **Conclusion**: After analyzing all options, the correct answer is that Monascus purpureus is commercially used in the production of blood cholesterol-lowering statins.

**Final Answer**: C) Blood cholesterol-lowering statins
