C1 Biorefinery by Designer Microbes |
초록 |
The designer microbes are a key biological technology that can be used for biorefinery. The use of complexed enzyme systems is one of the strategies for effective bioresources utilization and offers considerably greater potential through a highly ordered structural organization that enables enzyme proximity synergy. Carbon monoxide (CO) was successfully efficiently converted by functional complexes containing carbon monoxide dehydrogenase and carbon monoxide sensing heme protein with enhanced CO binding affinity. Carbon monoxide sensing heme protein acts as mediator for increasing of carbon monoxide dehydrogenase activity by substrate proximity and assembled complexes caused an efficiently conversion of CO gas with aid of Carbon monoxide sensing heme protein. An enzyme complex for biological conversion of CO to CO2 was anchored on the cell surface of CO2-utilizing Ralstonia eutropha and successfully showed 3.3-fold increased conversion efficiency. These results suggest that the complexed system may be a promising strategy for C1 biorefinery as biological tools. |
