Abstract
In this invention, a process for producing fermentable sugars derivable from biomass that contains polysaccharide, such as cellulose, which has been made increasingly accessible as a substrate for enzymatic degradation or other methods of depolymerization. The process of the present invention increases accessibility of polysaccharides, typically present in biomass and produces polysaccharides with increased accessibility. The polysaccharides with increased accessibility may be subsequently saccharified to yield fermentable sugars. These fermentable sugars are subsequently able to be fermented to produce various target chemicals, such as alcohols, aldehydes, ketones or acids.
