Abstract

En esta invención, un proceso para producir azúcares fermentables derivables de biomasa que contienen polisacárido, tal como celulosa, que se ha hecho cada vez más accesible como un sustrato para degradación enzimática u otros métodos de despolimerización. El proceso de la presente invención incrementa la accesibilidad de polisacáridos, típicamente presentes en la biomasa y produce polisacáridos con accesibilidad incrementada. Los polisacáridos con accesibilidad incrementada pueden ser subsiguientemente sacarificados para producir azúcares fermentables. Estos azúcares fermentables son subsiguientemente capaces de ser fermentados para producir varios compuestos químicos, tales como alcoholes, aldehídos, cetonas o ácidos.
