Enzyme catalyst immobilized on porous fluoropolymer support

摘要

Enzyme catalyst immobilized on porous fluoropolymer supports. Catalytically active enzymes can be bound to a variety of fluoropolymer supports for use as a reaction catalyst. Moreover, consistently high rate of conversion during catalyst re-use over time is achieved. Furthermore, inactive enzyme catalyst can be stripped from the support and fresh enzyme can be bound to the support to achieve the original conversion rate. The immobilization of catalytic enzymes on porous fluoropolymers is a viable and novel technology for the preparation of advantaged catalysts.
