Abstract

A mech. stable tentacle affinity support has been produced by coating polystyrene beads with polyvinyl alc., coupling dextran tentacles, and subsequently attaching Cibacron blue as a biomimetic ligand. Binding studies using lactate dehydrogenase allowed the effects of ligand d. on binding kinetics and capacity to be detd. Increasing dye loading leads to a decrease in binding capacity but an increase in affinity. The kinetics of binding of lactate dehydrogenase to the tentacle adsorbent showed an operational rate const. that was four times greater than that of obtained with a porous beaded support of similar diam. The tentacle adsorbent had a max. binding capacity approx. 25% of that for the corresponding porous beaded support. Packed bed studies of the flow/pressure drop relationship suggest that the tentacle support can be used over a wider range of flow conditions and could be capable of greater productivity than comparable porous materials.
