Abstract

é aqui fornecido um processo para a produção de um produto de fermentação a partir de uma matéria prima lignocelulósica. o processo compreende imergir uma matéria prima lignocelulósica em uma solução aquosa para produzir uma matéria prima encharcada. a matéria prima encharcada tem a água pelo menos parcialmente removida e a matéria prima com a água parcialmente removida é submetida a pré-tratamento. o produto químico de pré-tratamento é dióxido de enxofre, ácido sulfuroso ou uma combinação dos mesmos e pode ser adicionado ao processo em qualquer estágio antes e/ou durante o pré-tratamento. a composição de matéria prima pré-tratada é alimentada a uma hidrólise enzimática conduzida a uma temperatura que é mais alta do que 58°c. a celulose na matéria prima pré-tratada é hidrolisada com enzimas celulase na presença dos sólidos dissolvidos para produzir glicose. a glicose é fermentada para produzir o produto de fermentação.
