What is a single cell protein? How is it significant for human welfare?

Explanation

Single cell protein (SCP) refers to dried microbial cells or total protein extracted from pure microbial cell culture. SCP is not pure protein. It refers to the whole cells of bacteria, yeast, filamentous fungi or algae. It also contains carbohydrates, lipids, nucleic acids, mineral salts and vitamins. The composition depends upon the organism and the substrate on which it grows.
Significance for human welfare :
They can be used as a protein supplement for both humans or animals. Microorganisms like algae, fungi, yeast and bacteria have very high protein content in their biomass.
(ii) It is cost effective and easy to digest.
(iii) Reduces pressure on agriculture.
(iv) The fat content is low and there is no pathogenicity and toxicity present in SCP.
