Abstract
The present invention provides for a method to deconstruct a biomass comprising: (a) introducing one or more individual components of an ionic liquid (IL) or deep eutectic solvent (DES) to a biomass, wherein the one or more individual components, and optionally any components already present in the biomass, form an IL or DES, or mixture thereof, which solubilizes the biomass to form a solubilized biomass mixture, wherein at least one individual component is introduced to the biomass separately from any other individual component; (b) optionally introducing an enzyme and/or a microbe to the solubilized biomass mixture such that the enzyme and/or microbe produces a sugar from the solubilized biomass mixture; and, (c) optionally separating the sugar from the solubilized biomass mixture.
