Abstract
Se divulgan en el presente procesos para la producción de etanol a partir de una materia prima lignocelulósica. Estos procesos proporcionan DMR de biomasa lignocelulósica que comprende desacetilación de dos etapas seguida por refinación mecánica para aumentar la producción de azúcar fermentable mientras se reducen los requisitos de carga de enzimas hidrolíticas.
