Culture broths of cellulolytic fungi were used together with commercial amylases to enhance the saccharification of cassava starch slurry. It was found that the addition of appropriate concentration of the cellulases Trichoderma viride and a soil isolated Basidiomycete , increased both the rate of sugar formation and the degree of solubilization, and decreased the viscosity of the hydrolyzates. Owing to the improvement of the rheological properties of the must, and the additional sugar produced, an increased ethanol yield would be expected from the alcoholic fermentation of this hydrolyzate.
