Question

What is a single- cell protein? Mention the uses of single- cell protein.

Answer 1

Hint: These are refined, or edible protein extracted from the dried cell biomass through microbial culture. They are mainly used as protein supplements for both humans and animals.

Correct step by step answer:
The crude, pure and refined, or edible protein extracted from the microorganisms are the single- cell protein. The microorganisms like algae, fungi, yeast, and bacteria have very high protein content in their biomass. These microbes are often grown using inexpensive substrates like agricultural waste viz. wood shavings, sawdust, corn cobs, etc. and even human and animal waste. They can be used as a protein supplement for humans and also for the animals.
Uses of single- cell protein:
- Single- cell protein offers an unconventional solution to the problem of protein deficiency being faced by the entire humanity.
- It provides instant energy and is extremely good for the health of eyes and skin.
- It serves as a great source of vitamins, amino acids, minerals, crude fibers, etc.
- It also provides the best protein supplemented food for undernourished children.
- Also used as therapeutic and natural medicines for controlling obesity, also lowers the blood sugar level in diabetic patients, reducing body weight and stress.
- It prevents the accumulation of cholesterol in the body.
- Other than all the above uses it is also used cosmetic products, like Biolipstics, herbal face cream, etc.

Note:
- Microorganisms have a high rate of multiplication, which means a large quantity of biomass can be produced in a comparatively shorter duration.
- To vary the amino acid composition the microbes can be easily genetically modified.
- A broad variety of raw materials can be used as a substrate including waste materials. This utilization of waste materials helps in decreasing the number of pollutants.and its production is independent of climatic conditions.
- In poultry it serves as an excellent and convenient source of proteins and other nutrients, it is widely used for feeding cattle, birds, fishes, etc.
