Which of the following is an algal source of SCP?

Options

A. Candida
B. Methanobacillus
C. Chlorella
D. Saccharomyces

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for an algal source of Single Cell Protein (SCP). SCP refers to protein derived from single-celled organisms, which can include algae, bacteria, and fungi.

2. **Identifying the Options**: The options given are:
- A) Candida
- B) Methanobacillus
- C) Cholera
- D) Saccharomyces

3. **Analyzing Each Option**:
- **Candida**: This is a genus of yeast, which is a type of fungus, not an algae. Therefore, it is not an algal source of SCP.
- **Methanobacillus**: This is a type of bacteria. Since it is not an algae, it cannot be considered an algal source of SCP.
- **Cholera**: This refers to a genus of unicellular algae that is rich in proteins. It is indeed an algal source of SCP and is used as a food supplement.
- **Saccharomyces**: This is also a yeast (fungus) and not an algae, making it incorrect as an algal source of SCP.

4. **Conclusion**: The only option that is an algal source of Single Cell Protein is **C) Cholera**.

**Final Answer**: C) Cholera
