Abstract

Se divulga una etapa de prehidrólisis mejorada que comprende exponer una biomasa lignocelulósica pretratada insoluble en agua a condiciones de vacío, con o sin enzimas. Después de exponer la biomasa lignocelulósica pretratada insoluble en agua a condiciones de vacío, la hidrólisis enzimática se efectúa en el material pretratado. El resultado es un mayor rendimiento de glucosa y, a menudo, xilosa, después de la hidrólisis enzimática, en comparación con una composición que no ha sido expuesta a condiciones de vacío.
