Steroids are crystallisable lipids. Utility of Rhizopus stolonifer fungus for steroid conversion was shown by

Options

A. Kohler and Milstein
B. Murray and Peterson
C. Waksman
D. Pasteur and Joubert

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the utility of the fungus Rhizopus stolonifer in the conversion of steroids, specifically which scientists demonstrated this utility.

2. **Identifying the Key Concepts**:
- Steroids are a type of crystallizable lipid.
- Rhizopus stolonifer is a fungus known for its ability to convert steroids through a biochemical process.

3. **Understanding the Process**:
- The conversion of steroids involves a process called hydroxylation.
- Hydroxylation is the addition of hydroxyl groups (-OH) to the steroid structure, which is essential for the formation of various steroid compounds.

4. **Researching the Scientists**:
- The question provides four pairs of names: Kohler and Millicent, Murray and Peterson, Wexman, and Pasteur and Jobart.
- We need to identify which pair is associated with the research on Rhizopus stolonifer and steroid conversion.

5. **Finding the Correct Answer**:
- The correct answer is that the utility of Rhizopus stolonifer for steroid conversion was shown by **Murray and Peterson**.

6. **Final Conclusion**:
- Therefore, the answer to the question is **Murray and Peterson**.
