The Dosa is a fermented product of Rice . The fermentation is carried out with the help of .

Options

A. Leuconostoc mesentroids
B. Streptococcus faeialis
C. Pedicococcus cerevisiae
D. Fusarium

Answer

To answer the question regarding the fermentation process of dosa, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Fermentation**:
- Fermentation is a metabolic process that converts sugars to acids, gases, or alcohol in the absence of oxygen. It is commonly used in food production.

2. **Identifying the Substrate**:
- In the case of dosa, the substrate used for fermentation is rice. Rice contains starch, which is broken down into sugars during the fermentation process.

3. **Microorganisms Involved**:
- The fermentation of rice for dosa is primarily carried out by specific microorganisms. In this case, the bacteria responsible for the fermentation are **Leuconostoc mesenteroides**.

4. **Role of the Microorganism**:
- Leuconostoc mesenteroides helps in breaking down the sugars present in rice, producing carbon dioxide (CO2) and other byproducts that contribute to the texture and flavor of the dosa.

5. **Conclusion**:
- Therefore, the fermentation of dosa is carried out with the help of the bacteria **Leuconostoc mesenteroides**.

### Final Answer:
The fermentation of dosa is carried out with the help of the bacteria **Leuconostoc mesenteroides**.
