Laccase　is　an　efficient　biocatalyst　for　oxidative　polymerization　of　organic　substrates.　However,　cost　of　enzyme　preparation,　low　stability　and　residual　protein　diminish　the　efficiency　of　laccase　mediated　polymerization.　In　this　work,　a　series　of　silicon　dioxide　coated　ferroferric　oxide　magnetic　nanoparticles　were　modified　by　different　functional　groups　including　γ-methacryloxypropyltrimethoxy,　succinic　anhydride,　glutaraldehyde　and　polyethylene　imine.　Infrared　spectra　indicated　the　magnetic　carriers　have　been　successfully　modified.　Vibrating　sample　magnetometer　(VSM)　analysis　revealed　that　all　of　these　carriers　showed　high　magnetic　responsiveness　after　the　surface　functionalization.　Laccase　from　Cerrena　sp.　HYB07　was　then　respectively　immobilized　covalently　on　these　functionalized　magnetic　carriers.　All　the　immobilized　laccases　displayed　higher　thermostability　than　free　laccase　and　glutaraldehyde　functionalized　support　(named　FSNG)　immobilized　laccase　showed　better　performance.　These　immobilized　laccases　all　showed　higher　efficiency　than　free　laccase　for　oxidative　polymerization　of　catechol　and　hydroquinone.　The　immobilized　laccases　could　be　separated　from　the　water　insoluble　polymerization　products.　The　polymerization　product　of　hydroquinone　by　FSNG　immobilized　laccase　showed　the　average　polymerization　degree　of　the　poly(hydroquinone)　was　six　(DP=6).　This　work　provided　a　comprehensive　exploration　of　laccase　immobilization　on　magnetic　carrier　for　catalyzing　polymerization　of　phenols.　©　2023　Elsevier　Inc.
