Trichoderma harzianum has attracting attention for its potential alternative use in biofuel production, due to a recognized competence for high diversity glycoside hydrolases (GH) enzyme complex, including higher β-glucosidases and auxiliary proteins, using low-cost carbon sources. This strain constitutively overexpressed the global regulator putative methyltransferase - LAE1, in order to improve the GHs production. The recombinant strain achieved 79-fold increase in lae1 expression and high GHs productivity.

This work investigates the influence of the positive regulator XYR1 of Trichoderma harzianum on the production of cellulolytic enzymes, using sugarcane bagasse as carbon source. Constitutive expression of xyr1 was achieved under the control of the strong Trichoderma reesei pki1 promoter. Five clones with xyr1 overexpression achieved higher xyr1 expression and greater enzymatic productivity when cultivated under submerged fermentation, hence validating the genetic construction for T.
