What happens when Gram positive bacteria are treated with lysozyme ?

Options

A. Their plasma membrane gets dissolved
B. Their genetic material gets dissolved
C. Their cell wall gets dissolved
D. Cell can not survive in high glucose concentration

Answer

**Step-by-Step Solution:**

1. **Understanding Gram Positive Bacteria**:
- Gram positive bacteria have a thick peptidoglycan layer in their cell wall, which is crucial for maintaining their structural integrity.

2. **Role of Lysozyme**:
- Lysozyme is an enzyme that specifically targets the peptidoglycan layer of bacterial cell walls. It hydrolyzes the bonds in the peptidoglycan, leading to the breakdown of the cell wall structure.

3. **Effect of Lysozyme on Gram Positive Bacteria**:
- When gram positive bacteria are treated with lysozyme, the peptidoglycan layer is degraded. This results in the weakening of the cell wall.

4. **Consequences of Cell Wall Dissolution**:
- As the cell wall is compromised, the bacteria can no longer maintain their shape and structural integrity, leading to cell lysis (bursting) and death of the bacteria.

5. **Comparison with Gram Negative Bacteria**:
- It is important to note that lysozyme has a limited effect on gram negative bacteria due to their outer membrane, which protects the peptidoglycan layer from lysozyme action.

6. **Conclusion**:
- Therefore, the correct answer to the question is that when gram positive bacteria are treated with lysozyme, their cell wall gets dissolved.

**Final Answer**: Their cell wall gets dissolved.
