Question

It has been observed that about 250 g of Methylophilus methylotrophus produces 25 tonnes of protein per day. How much of Methylophilus is required to produce 1 kg of protein in the same period?

• A. 2 g
• B. 0.002 g
• C. $1\times {10}^{-5}$
• D. 0.0002 kg

Answer 1

The correct option is C $1\times {10}^{-5}$

Cells from microorganisms such as bacteria, yeasts, filamentous algae are treated and used as food. It is called the Single Cell Protein (SCP).

Methylophilus methylotrophus is a bacteria used as Single Cell Protein.

As given in the question, 250 g (0.25 kg) of Methylophilus methylotrophus produces 25 tonnes of protein per day (25000 kg/day).

Find : Amount of Methylophilus required to produce 1 kg of protein.

Solution: 25000 kg of protein is produced by 0.25 kg of Methylophilus methylotrophus.

Then, 1 kg of protein is produced by $\frac{0.25}{25000}=1x{10}^{-5}$kg of Methylophilus methylotrophus
