Which one of the following fungi is used in baking of bread?

Options

A. Rhizopus stolonifer
B. Saccharomyces cerevisiae
C. Zygosaccharomyces octosporus
D. Penicilliurn notatum

Explanation

To solve the question of which fungi is used in the baking of bread, we can follow these steps:

### Step 1: Understand the Question
The question asks specifically about fungi that are used in the baking process of bread. We need to identify the correct type of fungi from the given options.

### Step 2: Analyze the Options
The options provided are:
a. Rhizopus stolonifer
b. Saccharomyces cerevisiae
c. Zygosaccharomyces octosporus
d. Penicillium notatum

### Step 3: Research Each Option
- **Rhizopus stolonifer**: This fungus is commonly known as black bread mold. It is not used in baking but is involved in the spoilage of bread.

- **Saccharomyces cerevisiae**: This is known as baker's yeast. It is widely used in baking as it ferments sugars and produces carbon dioxide, which helps the dough rise.

- **Zygosaccharomyces octosporus**: This yeast is used in food preservation but is not typically used in bread baking.

- **Penicillium notatum**: This fungus is known for producing penicillin and is not used in baking.

### Step 4: Identify the Correct Answer
Based on the analysis, **Saccharomyces cerevisiae** is the only option that is specifically used in the baking of bread due to its fermentation properties.

### Conclusion
The correct answer to the question is **b. Saccharomyces cerevisiae**.
