Production and Partial Characterization of Cellulases from Trichoderma sp. IS-05 Isolated from Sandy Coastal Plains of Northeast Brazil
Figure 3
Effect of pH on cellulase activity at 60°C produced by Trichoderma sp. IS-05 (a) grown on 4.4% (w/v) WB, 0.25% (w/v) peptone, and commercial enzyme CAREZYME (b). The ionic strength for all buffers was 50 mM: glycine-HCl (◆); sodium citrate (■); sodium phosphate (▴); Tris-HCl (∙); glycine-NaOH (-x-). Residual activity is expressed as a percentage of the original activity. Error bars represent the standard deviation of each experimental point (n = 2) (100% residual activity = 1079.7 U L−1).
