The microbe used for making bread is

Options

A. Saccharomyces cervisiae
B. Saccharomyces ellipsoidens
C. Saccharomyces pireformis
D. Saccharomyces sake

Answer

### Step-by-Step Solution:

1. **Identify the Context**: The question asks for the microbe used in making bread, which indicates we are looking for a microorganism involved in the baking process.

2. **Consider the Options**: The options provided are:
- Saccharomyces cerevisiae
- Saccharomyces eliposidens
- Saccharomyces pyriformis
- Saccharomyces sacre

3. **Recall the Role of Yeast in Baking**: Yeast is a crucial ingredient in bread-making. It is a type of fungus that ferments sugars, producing carbon dioxide and alcohol in the process.

4. **Understand the Fermentation Process**: During fermentation, yeast converts sugars into ethanol (C2H5OH) and carbon dioxide. The carbon dioxide produced is what causes the bread dough to rise, creating a fluffy texture.

5. **Identify the Correct Microbe**: Among the options, Saccharomyces cerevisiae is the most commonly used yeast in baking. It is known for its ability to ferment sugars effectively, making it ideal for bread production.

6. **Conclusion**: The microbe used for making bread is **Saccharomyces cerevisiae**.
