Fig. 1. Kinetics of the cellulolytic and ligninolytic enzymes production under three fermentation modes.Penicillium crustosum, Fusarium nygamai, Trichoderma capillare, and Aspergillus calidoustus were cultivated during 15 days of dark incubation without agitation, and olive stones were used as substrate. Experiments were carried out in constant temperature (28°C), inoculum size (107 spores), moisture content (75%), and pH (5.5) conditions.
