Current Research Activities

Biological Systems and Organisms

Current research activities are focusing on developing green enzymatic processes to replace chemical ones; developing enzymatic toolboxes to promote the usage of biocatalysis in chemical synthesis, enantioselective reactions in particular; developing high-performance cellulose-degrading enzymes (systems) for economic production of cellulose-based ethanol. We are applying microorganism screening, microbial metagenome screening, and directed molecular evolution techniques for novel enzyme finding and modification, and developing chemical and biochemical processes to use the enzymes in the production of value-added substances. Also, part of the work explores the potential of extracellular vesicles for a variety of biomedical and environmental applications. In addition, the work is focusing on harnessing the power of microbes as for biomedical and environmental applications.
