METHODS AND COMPOSITIONS FOR THE TREATMENT OF CELLULOSIC BIOMASS AND PRODUCTS PRODUCED THEREBY

摘要

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.
