Abstract
Defferent nitrogen Sources (Urea,monoammonium phosphate (MAP),Compound Nitrogen Phosphate Fertilizer (NP) ,Ammonium Sulphate (NH4)2SO4 and phosphate urea)were used as supplements for growing yeast (Saccharomyces cerevisiae )on fermentation medium containing 10%crushed,processed corn cob and molasse as carbon source.Results revealed supplementation the medium with5% urea and 4% molasse gave the highest growth yield of yeast and increased the crude protein from2.4%(in the untreated corncob) to 22% after fermentation. The second nitrogen source effect was MAP+ammonium sulfate yealding 17%crude protein, while MAP+Urea yield 13.125%. The experiments were conducted in shaker incubator at 30cº,pH5,150rpm for 72hrs.
