Stable cellulase immobilized on graphene oxide@CMC-g-poly(AMPS-co-AAm) hydrogel for enhanced enzymatic hydrolysis of lignocellulosic biomass

This study indicated tailoring efficient polymer-enzyme bioconjugates with superb stability and activity for practical utilization of cellulase enzyme in hydrolyzing lignocellulosic biomass. To this goal, a dual crosslinking (DC) strategy was presented to synthesize novel 3D networks of carboxymethyl cellulose grafted copolymers of 2-acrylamido-2methyl propane sulfonate and acrylamide (CMC-g-poly(AMPS-co-AAm)) hydrogels.
