Penicillium roqueforti and P. camemberti are responsible for

Options

A. Pathogenic diseases in man
B. Pathogenic diseases in plants
C. Imparting flavours to cheese and ripe fruits
D. None of the above

Answer

**Step-by-Step Solution:**

1. **Identify the Organisms**: The question mentions two specific species of fungi: Penicillium roqueforti and Penicillium camemberti.

2. **Understand the Characteristics of the Genus**: Both species belong to the genus Penicillium, which is part of the Ascomycota division. This genus is known for its diverse roles in various ecosystems, including both beneficial and pathogenic effects.

3. **Evaluate the Options**:
- **Pathogenic Diseases in Man**: This option is incorrect. Neither Penicillium roqueforti nor P. camemberti are known to cause diseases in humans. In fact, some Penicillium species produce antibiotics that can protect humans from pathogens.

- **Pathogenic Diseases in Plants**: This option is also incorrect for the two species in question. While some Penicillium species can be pathogenic to plants, P. roqueforti and P. camemberti do not cause diseases in plants.

- **Imparting Flavor to Cheese and Dry Fruits**: This option is correct. Penicillium roqueforti is specifically used in the production of blue cheese, contributing to its distinct flavor and color. Similarly, Penicillium camemberti is used in the production of soft and hard cheeses and plays a role in the ripening of fruits through the secretion of enzymes.

- **None of the Above**: This option is incorrect since option C is correct.

4. **Conclusion**: Based on the evaluation, the correct answer is that Penicillium roqueforti and P. camemberti are responsible for imparting flavor to cheese and dry fruits.

**Final Answer**: Imparting flavor to cheese and dry fruits.
