Which one of the following is a wrong matching of a microbe and its industrial product, while the remaining three are correct,

Options

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

Answer

To solve the question regarding the wrong matching of a microbe and its industrial product, we can follow these steps:

### Step 1: Identify the Microbes and Their Products
We need to list the microbes mentioned in the options along with their corresponding industrial products. This will help us determine which one does not match correctly.

### Step 2: Verify Each Matching
For each microbe-product pair, we need to verify if the product is indeed derived from the specified microbe.

1. **Streptococcus** - Known for producing **Streptokinase**, which is used as a clot buster.
2. **Fungi (e.g., Penicillium)** - Produces **Penicillin**, an antibiotic.
3. **Fungi (e.g., Tolypocladium inflatum)** - Produces **Cyclosporine A**, an immunosuppressant.
4. **Yeast (e.g., Saccharomyces cerevisiae)** - Produces **Statins**, which are used to lower cholesterol.

### Step 3: Identify the Incorrect Pairing
After verifying each pairing, we can identify which one does not correctly match the microbe with its product.

- **Streptococcus - Streptokinase**: Correct
- **Penicillium - Penicillin**: Correct
- **Tolypocladium - Cyclosporine A**: Correct
- **Saccharomyces - Statins**: Incorrect (Statins are not produced by yeast; they are typically synthesized chemically or derived from fungi.)

### Conclusion
The wrong matching of a microbe and its industrial product is **Saccharomyces - Statins**.
