ABSTRACT
Different concentrations of the unconventional culture medium of cow waste extracted under different temperatures [22,100 and 120°C]were used for the production of single cell protein from Chlorella pyrenoidosa [strain 251 UTEX]. Under any of the extraction temperatures utilized, the waste supported a gradually increasing algal growth, reaching maximum at a waste concentration of 1.5% then decreased to a minimum at the highest concentration [4.5%]. However the extract prepared by boiling proved to be the best of all [for maximum growth] under the optimum waste cocentration. The protein amino acid profile showed a marked variation in the alga cultured on both waste and carol synthetic media. A considerable amount of the important amino acid Lysine was recorded in the protein amino acid profile of Chlorella grown on the waste medium comparable to that in the FAO reference protein
