Enzymatic deconstruction of semidilute hemicellulose solutions
Enzymes that degrade lignocellulose are extensively studied by biochemists for developing eco-friendly transformation processes of plant biomass into fuels or plastics. However, little is known about the exact deconstruction course of "real" biomass materials. One fundamental objective is to characterize the action of the enzymes in conditions where the local concentration of polymer is elevated. We propose to contribute to this objective by following with SANS the deconstruction of semidilute arabinoxylan (AX) solutions in which enzymes are dispersed at time zero. We plan to determine precisely the variations of the characteristic lengths of the polymer as hydrolysis occurs. We will then analyze these variations using different scenarios for enzyme's generic behavior in concentrated polymeric systems.
