3.4.4. Amylase production
The majority of Trichoderma spp. wild isolates (4 of 6) were better amylase producers than A. niger (Fig. 7). Production of amylase is not expected considering the results shown in Fig. 7A. Isolate T. harzianum T10 produced the highest level of amylase, in addition to the highest xylanase production level already observed. Amylase isoforms were detected in T. koningii TK1, T. atroviride TA1 and T. atroviride T42 isolates.
