A two-step method for activating a cellulosic feedstock is described. The feedstock is subjected to a first high temperature activation step at a temperature greater than 190 C. and a second activation step at a lower temperature under alkali conditions. Also described are methods and compositions for the enzymatic hydrolysis of activated cellulose using one or more cellulase enzymes, a surfactant and polyaspartic acid. Also described are products of the methods.

The present invention relates to a method for effectively recovering a sugar solution containing glucose and saccharogenic residues after saccharification using an acid or a saccharification enzyme of a wood-based or algae biomass, and a device for implementing the method. More specifically, the present invention relates to a method capable of recovering a sugar solution using minimal equipment and water after aggregating fine particles by adding a protein suspension to a suspension of glucose and saccharogenic residues which are produced by saccharifying cellulose by adding an acid or saccharification enzyme to the biomass, while capable of minimizing an amount of saccharide lost in the residues, and a device for implementing the method.
