Anti-coagulent nature of endospore is due to the presence of

Options

A. Teichoic acid
B. Ca-dipicolinic acid
C. Diaminopimelic acid
D. Calcium pectate

Answer

To solve the question regarding the anti-coagulant nature of endospores, we need to analyze the options provided and understand the components of endospores.

### Step-by-Step Solution:

1. **Understanding Endospores**:
- Endospores are specialized structures formed by certain bacteria (like Bacillus and Clostridium) to survive in harsh environmental conditions. They are highly resistant to heat, desiccation, and chemicals.

2. **Identifying the Components**:
- The question asks about the anti-coagulant nature of endospores. We need to focus on the components that contribute to this property.

3. **Analyzing the Options**:
- **Option A: Teichoic Acid**: This is a component of the cell wall in Gram-positive bacteria but does not relate to endospores.
- **Option B: Calcium and Dipicolinic Acid (DPA)**: Calcium is known to stabilize the structure of endospores, and DPA is crucial for the heat resistance and stability of endospores.
- **Option C: Diaminopimelic Acid**: This is a component of peptidoglycan in bacterial cell walls and does not directly relate to endospores.
- **Option D: Calcium Pactate**: This is not a recognized component associated with endospores.

4. **Conclusion**:
- The correct answer is **Option B: Calcium and Dipicolinic Acid**. These two components are essential for the anti-coagulant nature of endospores, helping them survive in unfavorable conditions.

### Final Answer:
The anti-coagulant nature of endospores is due to the presence of **Calcium and Dipicolinic Acid**.
