Abstract: The enzyme activities of Trichoderma viride and Aspergillus niger grown on various waste cellulosic materials such as corncobs; saw dust and sugarcane baggase were tested for a period of 192 hrs. The maximum activity of 0.33 mg/min/ml & 0.026 mg/min/ml of cellulase enzyme were found to be produced on saw dust after 144 hrs by Aspergillus niger & Trichoderma viride; respectively. Corncob showed the highest activity at 120 hrs of 0.22 mg/min/ml & at 96 hrs of 0.0246 mg/min/ml by Aspergillus niger & Trichoderma viride; followed by sugarcane with the highest activity of 0.026 mg/min/ml & 0.0256 mg/min/ml 120 hrs by Aspergillus niger & Trichoderma viride; respectively. From the above results; Aspergillus niger produced the highest amount of cellulase activity with sawdust as substrate followed by Trichoderma viride by solid state fermentation.
