Abstract

método para o tratamento de sacarificação enzimática de uma matéria-prima a base de lignocelulose. é provido um método para o tratamento de sacarificação enzimática de uma matéria-prima a base de lignocelulose, no qual uma matéria-prima a base de lignocelulose que foi submetida a um pré-tratamento para produzir a matéria-prima apropriada para uma reação de sacarificação enzimática é adicionada, junto com um eletrólito contendo um sal solúvel em água, na água contendo enzima de sacarificação de celulose; a matéria-prima a base de lignocelulose como uma suspensão de matéria-prima cuja condutividade elétrica foi ajustada em 5ms/cm a 25ms/cm, é submetido a um tratamento de sacarificação enzimática através de uma reação de sacarificação enzimática; o produto da reação e uma solução contendo enzima são separados e recuperados da suspensão tratada depois do tratamento de sacarificação enzimática; e a solução contendo enzima recuperada é reciclada como uma enzima para o processo de tratamento de sacarificação enzimática.
