A protein extracted from cultured algae, yeasts, or 
bacteria and used as a substitute for protein-rich foods, 
especially in animal feeds. 
	Microorganisms can be grown on a whole range of 
cheap or waste materials, harvested and then purified 
processed to provide food for either humans or livestock. 
If the foodstuff produced is a protein, the product is 
called single cell protein (SCP). Many microorganisms are 
suitable for this process, including algae, blue-greens, 
fungi and bacteria

Dried biomass of a single species of microbe that can be 
use as a protein source in the diet is known as single-cell 
protein.
