Abstract

A presente invenção trata de um bioprocesso enzimático para a produção de hidrolisados com elevadas concentrações de açucares fermentescíveis a partir de materiais de composição lignocelulósica, como resíduos agrícolas e florestais, in natura ou pré-tratados. As correntes produzidas, ricas em açucares, podem ser então fermentadas para produzir álcoois (etanol, butanol, xilitol), ácido orgãnico e outras moléculas de intereses para os sectores de biocombustíveis e petroquímico. Os materiais lignocelulósicos sólidos são adicionados em grandes quantidades e mantidos em contado com os preparados enzimáticos sob condições favoráveis de pH e temperatura, sob agitação constante, mesmo no início do processo, quando a matéria-prima ainda náo está completamente liquefeita. Ao longo do processo materiais lignocelulósicos sólidos, preparados enzimático e aditivos podem ser adicionados de forma intermitente.
