| dc.description.resumo | Lignocellulolytic enzymes have a great biotechnological potential. Their commercial exploitation has been considerably increased in recent years. However, its industrial application in the conversion of lignocellulosic biomass to biofuels depends on the development of more economical processes and technologies for the lignocellulolytic enzyme production. In this study, the improvement of cellulases and xylanases by Trichoderma reesei CCT-2768 production induced by pretreated carnauba straw with alkaline hydrogen peroxide (A-HP) was performed and its crude extract produced was applied in the enzymatic hydrolysis of sugarcane bagasse. Herein, three conditions were carried out consisting of changing solid loading, pretreatment time, and hydrogen peroxide concentration. The FPase, CMCase, xylanase, and β-glucosidase activities of produced crude extracts were measured. Pretreated carnauba straw had a higher production of total cellulase (2.4 U/g dry substrate) and xylanase (172 U/g dry substrate) enzymes. The low cellulases (8.0 U/g dry substrate) and high xylanase charges (544 U/g dry substrate) present in the produced extract and applied into pretreated sugarcane bagasse hydrolysis allowed a hydrolysis efficiency of 86.96%. The in situ lignocellulolytic enzyme production can represent a relevant advance in the future in overall cost reducing enzymatic hydrolysis process of lignocellulosic materials | pt_BR |
