The Trichoderma reesei and Sclerotium cepivorum requirements for cellulases production from beet pulp and olive cake were investigated with respect to their affinity to cellulases activities.
The appreciated nutrients were [NH4] 2 So4 [1.6 g/l] KH2 P04 [4.0 g/l] , Ca CL2 [0.4 g/l] , Mg So4 [0.6 g/l] , and Tween 80 [2.0 g/l] for T. reesei. However, these concentrations, in the same order, were 1.4, 3.0, 0.3, 0.3, and 2.0 g/l for S. cepivorum with substitution of [NH4] 2SO4 by NH4 H2 PO4. Vitamin B mixture seemed to be more suitable for T. reesei, whereas, sodium acetate was the best for S. cepivorum. Addition of 5.0% filter paper in the presence of 2.0% beet pulp resulted in the highest values of cellulase enzymes production and activities for both organisms
