Abstract

Se describe un proceso para producir azucares fermentables derivables a partir de biomasa que contiene polisacárido, tal como celulosa, se hace incrementada accesible como un sustrato para degradación enzimática u otros métodos de despolimerización. Estos azucares fermentables son subsecuentemente capaces de fermentarse para producir varios materiales químicos objetivo, tales como alcoholes, aldehídos, cetonas o ácidos.
