Abstract
The obtaining of enzymes with desirable physic-chemical characteristics at low cost is one of the major challenges in the biofuel research. Thus, the hydrolytic enzymes production by Trichoderma reesei mutant strains has been attracting interest in the industry sector. This microorganism has three positive activators (XYR1, ACE2 and HAP2/3/5 complex) and two repressors (ACE1 and CRE1) whi…
