The construct starts with a T7 promoter, followed by a ribosome binding site and the adhE gene. adhE encodes for fused acetaldehyde-CoAdehydrogenase and catalyzes the reaction of acetyl-CoA to ethanol in anaerobic fermentation conditions. Lastly, it has AmilCP as a reporter gene that will encode for blue chromoprotein as a visual indicator the bacteria took the plasmid. We made this construct based on the preliminary research as a way to enhance the fermentation process.

AdhE with AmilCP reporter

The construct starts with a T7 promoter, followed by a ribosome binding site and the adhE gene. adhE encodes for fused acetaldehyde-CoAdehydrogenase and catalyzes the reaction of acetyl-CoA to ethanol in anaerobic fermentation conditions. Lastly, it has AmilCP as a reporter gene that will encode for blue chromoprotein as a visual indicator the bacteria took the plasmid. We made this construct based on the preliminary research as a way to enhance the fermentation process.

Usage and Biology

According to the paper “Metabolic engineering of Escherichia coli for production of mixed-acid fermentation end products”, the main genes involved in the fermentation pathway of E. coli are alcohol dehydrogenase, pyruvate formate lyase, and pyruvate kinase. The image below depicts a diagram of this pathway. The AdhE enzyme sequentially reduces acetyl-CoA to acetaldehyde and then to ethanol under anaerobic conditions. This gene plays a vital role in the fermentation pathway, which is why our team developed a device to express more of this enzyme in E. coli and maximize the amount of ethanol produced in our project.
