Conversion of agricultural and industrial wastes for single cell protein production and pollution potential reduction:: A review

Single cell protein (SCP) is the dried form of various microorganisms, such as bacteria, fungi and algae, grown on various substrates. The most economic substrates used in SCP production are agricultural wastes and the Mediterranean district is rich in citrus residues, cotton stalk and residues after harvest in agricultural fields, but also sugar cane and cassava wastes are widely used in the world. SCP is used as animal feed and also supplemental feed stuff material. Thus, agricultural and industrial wastes can be evaluated as enriched animal feed and considered as human supplemental foodstuff for the future instead of being discarded to the environment. This work is a review related to the evaluation of wastes and also a contribution to prevent environmental pollution.
