Continuous production of maltooligosaccharides from glucose 1-phosphate by amylase-phosphorylase reactor

Using an ultrafiltration cell, the continuous production of maltose and a mixture of other oligosaccharides was achieved by the combined action of alpha- or beta-amylase and phosphorylase. For the beta-amylase-phosphorylase system, a steady production of maltose was obtained until the beta-amylase was inactivated. For the alpha-amylase-phosphorylase system, it was difficult to maintain a stable production of oligosaccharides, probably due to the destruction of substrate glycogen by random cleavage by alpha-amylase.
