✦ Synopsis

Ultraflltratlon modules, conslstlng of bundles of asymmetric hollow fibers, present many attractive features as lmmoblllzed enzyme reactors, the most important bemg the sunpllclty of the moblllzation and regeneration procedure, and the high specific actlvltles that can be achieved Thlsstudycontams a hydrodynamic and klnetlc analysx of a hollow fiber amyloglucosldase reactor for starch and maltose hydrolysis It first shows, from residence time dlstrlbutlon studies, that the actual number of perfused fibers can be considerably reduced if a too low flow rate IS utilized. Second It experimentally establishes the dependence of the reactor hydrolytic activity on the substrate concentration and on the flow rate. It moreover demonstrates the Important klnetlc Influence of external and internal diffusion llmltatlons as well as of the lnhlbltlon resulting from the produced glucose.
