| Description | Enzyme hydrolysis of soluble starch by free β-amylase and pullulanase for the production of maltose was done by the simultaneous use of a stirred tank reactor and an ultrafiltration membrane. Higher conversions of starch to maltose were obtained in the permeates than that in a batch reaction. Using the basic mass balance and rate equations, concentrations of maltose, maltotriose, and substrate in the retentates and permeates could be simulated effectively. More than 99.9% of enzyme was found to be rejected by the membrane. The obtained volumetric productivities were several times higher than those reported in other systems. This system was found to have high maltose productivity with a short mean residence time, being easily controlled by transmembrane pressure. |
