Statins commercialised as blood cholestrol lowering agent are produced by

Options

A. Yeast - Monascus purpureus
B. Bacterium - Monascus purpureus
C. Fungus - Trichoderma polysporum
D. Bacterium - Streptococcus

Answer

To solve the question regarding which organism produces statins, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Statins**: Statins are a class of drugs used to lower cholesterol levels in the blood. They work by inhibiting an enzyme involved in cholesterol production.

2. **Identifying the Source of Statins**: Statins are primarily produced by certain microorganisms. The question asks for the specific organism that commercializes statins.

3. **Reviewing the Options**: The options provided include yeast, bacteria, and fungi. We need to identify which of these is correct.

4. **Recognizing the Correct Organism**: The yeast known for producing statins is **Monascus purpureus**. This yeast is used in the fermentation process to produce statins.

5. **Eliminating Incorrect Options**:
- **Bacteria**: Monascus purpureus is not a bacterium; it is a yeast, so this option is incorrect.
- **Fungi**: While some fungi produce various compounds, **Trichoderma polysporum** is known for producing cyclosporine A, which is not related to statins.
- **Another Bacterium**: The mention of **Streptococcus** refers to the production of streptokinase, which is also unrelated to statins.

6. **Conclusion**: The correct answer is that statins are produced by the yeast **Monascus purpureus**.

### Final Answer:
Statins are produced by **Monascus purpureus** (yeast).
