The increase in industrial interest in biomass conversion to produce biofuels and valuable chemicals is driven by environmental concerns and oil shortages. Enzymes, such as cellulases, hemicellulases, and ligninolytic, show outstanding specificity towards their substrates and can be reused when immobilized onto magnetic nanocarriers. Various functionalization strategies for magnetic nanoparticles, such as silica-based surfaces, graphene oxide-based nanocomposites, and polymer-coated surfaces, have been highlighted for enzyme immobilization in biomass processing.
Environmental concerns, along with oil shortages, have increased industrial interest in biomass conversion to produce biofuels and other valuable chemicals. A green option in biomass processing is the use of enzymes, such as cellulases, hemicellulases, and ligninolytic (laccase and peroxidases), which have outstanding specificity toward their substrates and can be reused if immobilized onto magnetic nanocarriers. Numerous studies report the biocatalysts' performance after covalent binding or adsorption on differently functionalized magnetic nanoparticles (MNPs). Functionalization strategies of MNPs include silica-based surfaces obtained through a sol-gel process, graphene oxide-based nanocomposites, polymer-coated surfaces, grafting polymer brushes, and others, which have been emphasized in this review of the immobilization and co-immobilization of enzymes used for biomass conversion. Careful analysis of the parameters affecting the performance of enzyme immobilization for new hybrid matrices has enabled us to achieve wider tolerance to thermal or chemical stress by these biosystems during saccharification. Additionally, it has enabled the application of immobilized laccase to remove toxic organic compounds from lignin, among other recent advances addressed here related to the use of reusable magnetic carriers for bioderived chemical manufacturing.
