제목 Enhancing enzymatic reactive separation of a highly water insoluble substrate by using bicontinuous interfacially jammed emulsion gels (bijels) as media
초록 Enzymes are efficient catalysts capable of converting various substrates into desired products with high specificity under mild conditions. But, their catalytic activity can be reduced substantially when dealing with water-insoluble substrate. In this study, we use a bicontinuous interfacially jammed emulsion gel (bijel) which provides large interfacial area between oil and water, in purpose of promoting the enzymatic conversion with hydrophobic substrate. We show that bijels can be utilized as media by using lipase-catalyzed hydrolysis of tributyrin for a model reaction in a batch mode. The initial reaction rate increases four-fold in bijel system compared to a stirred biphasic medium. Our results demonstrate bijels as powerful tool for biphasic enzymatic reaction with various hydrophobic reagents, and as reaction media to enable continuous reactive separations.
