Abstract: Insolubilized enzyme particulates are located on the upstream surface of a filtration layer of a filtering element which can be used in a cartridge filter. Employed in a recycling flow reaction system at relatively high flux rates, the cartridges are useful for conducting catalyzed chemical reactions of dissolved solutes, for example, esterifications, isomerizations, oxidations, reductions, and cyclizations.

Abstract: The invention provides a method of separating a biomacromolecule which comprises the steps of providing a separation system including a filter element which comprises a composite filtration medium, the composite filtration medium comprising a filtration layer on the upstream surface of which are located insoluble stationary phase particulates, the particulates being capable of binding to a biomacromolecule or class of biomacromolecules, a reservoir containing a solution mixture comprising at least one biomacromolecule as solute, and a pump and associated tubing to form a closed loop assembly, and recirculation pumping the solution mixture through the filter cartridge so as to bind the at least one biomacromolecule to the stationary phase particulate so as to form a biomacromolecule:stationary phase particulate product.
