Options

A. Citric acid - Aspergillus flavus
B. Clot buster - Steptococcus
C. Cyclosporin A - Trichoderma
D. Butyric acid - Clostridium butylicum

Answer

To solve the question of selecting the incorrect match, we will analyze each option provided:

1. **Citric acid - Aspergillus flavus**:
- Citric acid is actually produced by the fungus **Aspergillus niger**, not **Aspergillus flavus**. Therefore, this match is incorrect.

2. **Clot buster - Streptococcus**:
- The term "clot buster" commonly refers to **streptokinase**, which is indeed produced by the bacterium **Streptococcus**. This match is correct.

3. **Cyclosporin A - Trichoderma**:
- **Cyclosporin A** is an immunosuppressive drug derived from the fungus **Trichoderma polysporum**. This match is also correct.

4. **Butyric acid - Clostridium butylicum**:
- **Butyric acid** is produced by the bacterium **Clostridium acetobutylicum** (sometimes referred to as Clostridium butylicum). This match is correct as well.

After evaluating all the options, we conclude that the incorrect match is:

**Answer: 1) Citric acid - Aspergillus flavus**
