Question

One of the alternate sources of protein for animals and human nutrition is?
A. Single cell protein
B. Non-vegetarian meal
C. Mushrooms
D. Pulses

Answer 1

Hint: The alternative sources of protein are derived from the pure or mixed culture of fungi, bacteria and algae.

Complete step by step answer: As the world population is tremendously increasing which leads to the shortage of food supplies. The standard agricultural production of cereals, vegetables, fruits or pulses not able to meet the demand of humans and animals. About one-fourth of the population is suffering from hunger and malnutrition. Therefore, alternative methods to meet the demand have to be evolved.
Option A – Single Cell Protein: It is the dead cell of microorganisms that are rich in protein. It is used as a protein supplement in animals and human nutrition. A most common example is Spirulina.
Option B- Non-vegetarian meal: It simply means, meals that contain all the non-vegetarian items in a meal such as egg, chicken, and all the meat items.
Option C- Mushrooms: Mushrooms are the edible fungi belonging to basidiomycetes. It is a fleshy, fruiting body of the fungus.
Option D- Pulses: The seeds or the fruit of the plants belong to the Fabaceae family are called legume or pulse. Pulses include peas, beans and lentils.
Hence, the correct answer is option A, i.e. Single Cell Protein.

Note: In a large scale, the microbes are grown as a source of protein. The common sources of SCP are yeast, algae and some bacteria. These microbes are rich in protein. Microbes can be easily grown on a waste substance like molasses, animal manure, sewage, waste water from potato processing plants. The microbes are growing on the waste materials, decreasing the environmental pollution. The SCP is rich in protein and low in fat.
