Abstract
Trichoderma reesei showed higher production of CMCase (3.65 times),FPase (3.68 times),xylanase (1.63 times), and hydrolytic power (5.4 times) than Aspergillus niger. However, p-glucosidase production was only about 0.135 of that of A. niger. Mixed cultivation of the two strains Trichoderma reesei and Aspergillus niger with modification of medium composition increased aN cenulase activities. It was 8.1 times for CMCase. 5.9 times for FPase, 1.2 times for P-glucosidase, 3.6 times for xylanase as compared with Aspergillus niger. The hydrolytic power (%) of the cellulase complex produced by the mixed culture was 15.5 times in comparison with Aspergillus niger. A comparative study was made on cellulase activities produced by the mixed cuhure and that reported by other cellulase producers. The cellulase enzymes production by mixed culture is comparable to that of cellulases potent producers
