It has been used a hollow fiber module NT-1808-S from Sorin Biomedica
with 5 kDa cuprophan membranes for the kinetic study of fructose-gluco
se isomerization with the soluble enzyme glucose-isomerase <<spezyme G
I>> from Genencor Internacional. The comparison of the experimental re
sults with the ones obtained with a perfect mixture reactor, shows tha
t in the hollow fiber reactor a perfect mixture reactor, shows that in
the hollow fiber reactor the inactivation of the enzyme-substrate see
ms to take place in the membrane polarization coat.
