Research Topic

Bioprocess Engineering

Our research focuses on the bioprocess engineering which includes both fermentation and separation processes. In the fermentation technology, efforts have been devoted to renewable resources utilization, waste oil biodegradation, periodical operation strategy and its associated dynamic behavior, in-situ inhibitor removal, insect ell/baculovrius expression system for recombinant protein (interleukin-5), serum-free media development, fermentation additive to enhance oxygen transfer and productivity. The applications of isoamylase were also investigated, which covers immobilization techniques and enhanced reaction under supercritical carbon dioxide. For downstream process, proteins/enzymes separation by adsorption, foam fractionation and chromatographic method as well as stability enhancement and refolding have been investigated.


 

Higee System

Process intensification by Higee system (rotating packed bed) could enhance mass transfer greatly; therefore, reduce the equipment size dramatically. Attractive applications in absorption, stripping, adsorption, are being experimentally demonstrated in our research results. Meanwhile, fundamental studies of design criteria are currently investigated.
