Question

what is single cell protein and its significance?

Answer 1

Single cell proteins or SCP refers to the source of proteins which are extracted from single cell organisms like algae, yeast, bacteria, and fungi normally grown on agricultural waste. These are produced with an intention to use them as the substitute for protein rich foods for humans and as well as for animals. Though SCP is a relatively modern concept, yet using microorganisms for food production and as animal feed supplement has been known to us since ages. Microorganisms have an ability to upgrade low protein content and this phenomenon was employed during First World War by Germans. Similarly, during Second World War other bacteria were used to replace the conventional food materials. Preteen was the first commercial single cell protein and was mainly used as animal feed supplement.
