文摘
Magnetic nanoparticles as supports for laccase immobilization for oxidative biocatalysis. The immobilized enzyme can be easily reused after simple magnetic separation. Immobilized laccase retained above 70% of initial activity after five reaction cycles. Immobilized laccase is a promising biomaterial for dye removal through biocatalyses.
