Which one of the following is used in the production of alcohol ? (A) Saccharomyces cerevisiae (B) Torulopsis utilis (C) Clostridium botulinum (D) Leuconostoc citrovorum

Options

A. Saccharomyces cerevisiae
B. Torulopsis utilis
C. Clostridium botulinum
D. Leuconostoc citrovorum

Answer

To solve the question of which organism is used in the production of alcohol, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks which organism is used in the production of alcohol. We need to identify the correct option from the given choices.

2. **Analyze the Options**:
- **(A) Saccharomyces cerevisiae**: This is a type of yeast commonly used in brewing and baking. It ferments sugars to produce alcohol and carbon dioxide.
- **(B) Torulopsis utilis**: This is another type of yeast, but it is primarily used for other purposes, such as in the production of certain food products.
- **(C) Clostridium botulinum**: This is a bacterium that produces a potent toxin and is not used for alcohol production.
- **(D) Leuconostoc citrovorum**: This is a lactic acid bacterium used in fermentation processes but not specifically for alcohol production.

3. **Identify the Correct Answer**: Among the options, **Saccharomyces cerevisiae** is well-known for its role in the fermentation process that produces alcohol. It is often referred to as "brewer's yeast" due to its extensive use in brewing industries.

4. **Conclusion**: Based on the analysis, the correct answer is **(A) Saccharomyces cerevisiae**.

### Final Answer:
(A) Saccharomyces cerevisiae
