Which one of the following is a wrong matching of a microbe and its industrial product,

Options

A. Yeast - statins
B. Acetobacter aceti - acetic acid
C. Clostridium butylicum - gluconic acid
D. Aspergillus niger - citric acid

Answer

To determine which of the following is a wrong matching of a microbe and its industrial product, we will analyze each option provided:

1. **Yeast produces statins**:
- Yeast is a type of fungus and is known for its role in fermentation. One of the products derived from yeast is statins, which are used to lower cholesterol levels in the blood.
- **Conclusion**: This is a correct matching.

2. **Acetobacter produces acetic acid**:
- Acetobacter aceti is a bacterium that is primarily known for its ability to convert ethanol into acetic acid, which is the main component of vinegar.
- **Conclusion**: This is a correct matching.

3. **Clostridium butylicum produces gluconic acid**:
- Clostridium butylicum is a bacterium that is known for producing butyric acid, not gluconic acid. Gluconic acid is typically produced by other microbes, such as certain strains of Aspergillus.
- **Conclusion**: This is a wrong matching.

4. **Aspergillus niger produces citric acid**:
- Aspergillus niger is a well-known fungus that is widely used in the industrial production of citric acid, which is used as a preservative and flavoring agent.
- **Conclusion**: This is a correct matching.

Based on the analysis, the wrong matching is:

**Clostridium butylicum produces gluconic acid.**
