Outline of Final Research Achievements

The novel membrane reactor system was developed using thermoresponsive Pickering emulsions as enzyme carriers. The thermoresponsive Pickering emulsion systems were successfully prepared by introducing thermoresponsive biopolymers to the system. The enzymatic reaction conditions in the system were obtained using a model enzyme. The concentration and recovery of the emulsions were successfully achieved by filtration process.
