Ethanol is commercially produced through a particular species of:-

Options

A. Saccharomyces
B. Clostridium
C. Trichoderma
D. Aspergillus

Answer

**Step-by-Step Solution:**

1. **Understanding Ethanol Production**: Ethanol is a type of alcohol that is commonly used as a biofuel and in various industrial applications. It can be produced through fermentation processes.

2. **Identifying the Organisms**: The question provides four options:
- A) Saccharomyces
- B) Clostridium
- C) Trichoderma
- D) Aspergillus

3. **Analyzing Each Option**:
- **Saccharomyces**: This is a genus of yeast, specifically Saccharomyces cerevisiae, which is widely known for its role in fermentation, particularly in the production of ethanol.
- **Clostridium**: This is a genus of bacteria that can produce ethanol, but it is not the primary organism used for commercial ethanol production.
- **Trichoderma**: This is a genus of fungi that is primarily used for biocontrol and enzyme production, not for ethanol production.
- **Aspergillus**: This is another genus of fungi, known for its role in fermentation and enzyme production, but not primarily for ethanol production.

4. **Conclusion**: Based on the analysis, the correct answer is **Option A: Saccharomyces cerevisiae**. This yeast is the primary organism used for the commercial production of ethanol.

**Final Answer**: Ethanol is commercially produced through a particular species of Saccharomyces cerevisiae.
