Abstract
A composition comprising mesoporous aggregates of magnetic nanoparticles and free-radical producing enzyme (i.e., enzyme-bound mesoporous aggregates), wherein the mesoporous aggregates of magnetic nanoparticles have mesopores in which the free-radical-producing enzyme is embedded. Methods for synthesizing the enzyme-bound mesoporous aggregates are also described. Processes that use said enzyme-bound mesoporous aggregates for depolymerizing lignin, removing aromatic contaminants from water, and polymerizing monomers polymerizable by a free-radical reaction are also described.
Claims19
A composition comprising self-assembled mesoporous aggregates of magnetic nanoparticles and a lactoperoxidase, wherein said lactoperoxidase is magnetically-entrapped without a bonding agent in mesopores of said self-assembled mesoporous aggregates of magnetic nanoparticles, and said lactoperoxidase functions by converting a diffusible substrate into a diffusible product.
A composition comprising self-assembled mesoporous aggregates of magnetic nanoparticles and an enzyme, wherein said enzyme is magnetically-entrapped without a bonding agent in mesopores of said self-assembled mesoporous aggregates of magnetic nanoparticles, and said enzyme functions by converting a diffusible substrate into a diffusible product, wherein said enzyme is selected from the group consisting of EC 1.1.2, EC 1.10.2, EC 1.14 oxidoreductase, cytochrome-b5 reductase, cytochrome-c reductase, and cytochrome-c peroxidase.
