There is a growing demand to produce bioethanol from inedible biomass – lignocellulose – to curtail emissions, maximize usage of agricultural and urban waste materials. Hydrolyzing cellulose to glucose is a critical step in the production of bioethanol from lignocellulose and can be accomplished through the use of enzymes, cellulases. This work shares the results obtained the stability of cellulases.<br/>The most common method of increasing the stability of enzymes is by immobilizing them to a support. This increased stability from immobilization stems from reduced biomolecule dynamics that may lead to conformational changes. The immobilized dynamics can be further reduced by increasing the number of attachment sites between the support and biomolecule and by increasing the density of biomolecule on the support. This work presents the findings of how functional group and biomolecule density on silica-coated iron oxide nanoparticles relate to the stability of immobilized cellulases.
