The reactor system combined with ultrafiltration (UF) membrane or hollow fiber tube is very useful for the continuous hydrolysis when the enzyme reaction is subjected to high polymer substrate such as protein and cellulose. The continuous bioconversion combined with hydrogenases and polymer-bound NAD (nicotinamide-adenine dinucleotide) was recently carried out by using UF membrane reactor. This type of bioreactor has more sophisticated biochemical function than the hydrolysis and the isomerization. The gel membrane containing microorganism or enzyme such as collagen-enzyme membrane has been applied as a biosensor in the field of analytical chemistry. The fiat gel membrane containing the yeast was recently applied to continuous ethanol production system, in which ethanol was efficiently produced for 5000 hrs by the yeast membrane. Polymerizable monomer combined with NAD, acrylamide and methylene-bisacrylamide was copolymerized in the presence of enzymes, and subsequently NAD and enzymes are entrapped in the gel membrane. The gel membrane is able to catalyze more sophisticated biochemical reactions such as oxygenation-reduction and biosynthesis by using the immobilized cofactors.
