 the future bioeconomy will rely heavily on lignosellulosic biomass, which is difficult to process due to its recalcitrant nature. Enzomatic conversion of cellulose, the most abundant and homogeneous polysaccharide in lignosellulosic biomass, is a key technology in future bio refineries, with recent discoveries in enzyme technology such as CBM33 and GH61 promoting efficiency by acting on the surfaces of insoluble substrates and introducing chain breaks without extracting them first.
