Outline of Final Research Achievements

Immobilized enzymatic methods are attracting attention as methods that can continuously utilize complex reactions that occur in vivo. Recently, we have established a process that enables continuous treatment of persistent phenolic compounds by immobilizing laccase, an oxidoreductase, on a substrate by electron beam graft polymerization. In this study, ultra-fine bubbles (UFB) was applied to further improve this process. The results obtained in this study suggest that the application of UFB to immobilized laccase can be expected to further improve the efficiency of removal of persistent substances.
