Formation of vinegar form alcohol is caused by

Options

A. Bacillus subtilis
B. Clostridium
C. Acetobacter aceti
D. Azotobacter

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the process of vinegar formation from alcohol and which organism is responsible for this conversion.

2. **Identifying the Options**: The options provided are:
- A) Bacillus subtilis
- B) Clostridium
- C) Acetobacter aceti
- D) Azotobacter

3. **Analyzing Each Option**:
- **Bacillus subtilis**: This is a non-pathogenic bacterium primarily used in agriculture and medicine as a probiotic. It does not play a role in vinegar formation.
- **Clostridium**: This genus includes pathogenic species that can cause food poisoning. It is not involved in the conversion of alcohol to vinegar.
- **Acetobacter aceti**: This bacterium is specifically known for its ability to convert ethanol (alcohol) into acetic acid (vinegar). This is the key organism responsible for vinegar production.
- **Azotobacter**: This is a nitrogen-fixing bacterium that does not participate in the fermentation process to produce vinegar.

4. **Conclusion**: Based on the analysis, the correct answer is **C) Acetobacter aceti**, as it is the organism that converts alcohol into vinegar.

5. **Final Answer**: The formation of vinegar from alcohol is caused by **Acetobacter aceti**.
