Abstract
An enzyme reactor system is provided based on the entrapment of an enzyme in a hydrogel layer coated on a support, and confined by an ultraporous thin film membrane diffusion barrier. The diffusion barrier confines the enzyme, but lets substrate and reaction products diffuse feeely into and out of the hydrogel layer. In an alternate embodiment, the support is formed of an ultraporous thin film membrane diffusion barrier on a microporous or macroporous support, through which the reaction products can diffuse freely, but through which neither enzyme nor substrate can pass. In this embodiment, the product is recovered in high purity, free of substrate and enzyme.
