250 g of Methylophilus methlotrophus can be expected to produce _______ tonnes of proteins.

Options

A. 15
B. 25
C. 40
D. 50

Explanation

To solve the question regarding how much protein can be produced from 250 g of Methylophilus methylotrophus, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Organism**: Methylophilus methylotrophus is a type of bacteria known for its ability to produce single-cell protein (SCP). It has a high biomass production rate, making it efficient for protein production.

**Hint**: Research the characteristics of Methylophilus methylotrophus and its role in protein production.

2. **Identify the Protein Yield**: According to the information provided, Methylophilus methylotrophus can produce approximately 25 tonnes of protein from 250 grams of the bacteria.

**Hint**: Look for data or studies that indicate the protein yield from Methylophilus methylotrophus.

3. **Calculate the Expected Protein Production**: Since 250 g of Methylophilus methylotrophus produces 25 tonnes of protein, we can directly state that the expected protein production from this amount of bacteria is 25 tonnes.

**Hint**: Remember that the question asks for the expected yield based on the given quantity of bacteria.

4. **Select the Correct Option**: From the options provided (15, 25, 40, 50), the correct answer is 25 tonnes.

**Hint**: Always verify your calculations against the options given in the question.

### Final Answer:
250 g of Methylophilus methylotrophus can be expected to produce **25 tonnes of proteins**.
