Options

A. Monscus purpureus - statins
B. Acetobacter aceti - Acetic acid
C. Clostridium butylicum - Lactis acid
D. Aspergillus niger - Citric acid

Answer

To solve the question, we need to identify the incorrect matching of a microbe and its industrial product from the given options. Let's analyze each option step by step.

### Step 1: Analyze Option A
- **Microbe**: Monascus purpureus
- **Product**: Statins
- **Analysis**: Monascus purpureus is a yeast that is known to produce statins, which are used as cholesterol-lowering agents. This match is correct.

### Step 2: Analyze Option B
- **Microbe**: Acetobacter aceti
- **Product**: Acetic acid
- **Analysis**: Acetobacter aceti is a bacterium that produces acetic acid, which is commonly used in vinegar and other industrial applications. This match is correct.

### Step 3: Analyze Option C
- **Microbe**: Clostridium butylicum
- **Product**: Lactic acid
- **Analysis**: Clostridium butylicum is known to produce butyric acid, not lactic acid. Lactic acid is typically produced by Lactobacillus species. Therefore, this match is incorrect.

### Step 4: Analyze Option D
- **Microbe**: Aspergillus niger
- **Product**: Citric acid
- **Analysis**: Aspergillus niger is a fungus that is widely used in the production of citric acid, which is a common additive in the food industry. This match is correct.

### Conclusion
The incorrect matching of a microbe and its industrial product is:
- **C: Clostridium butylicum - Lactic acid**

### Final Answer
The answer is **C: Clostridium butylicum - Lactic acid**.
