Abstract:

Single cell protein (SCP) was produced by propagation of two yeast strains, namely Saccharomyces cerevisiae NCYC 1530 and Candida utilis 70163 (DSMZ), on date syrup (Dips) substrate under different propagation conditions. The obtained SCP is intended to be used as fish and poultry feeding diets. The chemical composition, and hence eventually the nutritive value, of the so produced SCP was affected by the propagation conditions, especially the substrate feeding rate and the inoculum size at the beginning of fermentation. Under optimized propagation conditions, the amino acid composition of both yeast strains exhibited a good quality exhibiting most of the essential amino acids (for fish and poultry), especially lysine and sulfur containing amino acids. The biomass, especially that of S. cerevisiae, contained many essential vitamins of the B group. Moreover, the biomass of both yeasts contained high amounts of many important nutrient minerals such as calcium, manganese, iron and zinc. Fatty acids of the produced SCP were mostly of the preferred unsaturated ones.
