Which one of the following pairs is wrongly matched with respect to the product obtained from the respective microorganism

Options

A. Yeast - Ethanol
B. Streptomyces - Antibiotics
C. Coliforms - Vinegar
D. Methanogens - Gobar gas

Answer

To determine which pair is wrongly matched with respect to the product obtained from the respective microorganism, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Identify the Microorganisms and Products**:
- We need to look at each pair of microorganisms and their corresponding products.

2. **Evaluate the First Pair**:
- **Yeast → Ethanol**: Yeast is known for its role in fermentation, particularly in producing ethanol from carbohydrates. This pair is correctly matched.

3. **Evaluate the Second Pair**:
- **Streptomyces → Antibiotic**: Streptomyces is a genus of bacteria that is well-known for producing various antibiotics, including streptomycin. This pair is also correctly matched.

4. **Evaluate the Third Pair**:
- **Cauliforms → Vinegar**: Vinegar, which is acetic acid, is produced by the action of Acetobacter aceti, a type of bacteria, not Cauliforms. Therefore, this pair is incorrectly matched.

5. **Evaluate the Fourth Pair**:
- **Methanogens → Methane**: Methanogens are a group of microorganisms that produce methane as a metabolic byproduct. This pair is correctly matched.

6. **Conclusion**:
- The only wrongly matched pair is the third one: **Cauliforms → Vinegar**. The correct microorganism for vinegar production is Acetobacter aceti.

### Final Answer:
The wrongly matched pair is **Cauliforms → Vinegar**.
