PROJECT - Microbial Fuel Cell: The goal of this research is the manipulation of E.Coli; granting them the ability to release electrons in an aerobic enviroment. This project utilizes geobacter's cytocromes, which makes it's extracellular electron transfer possible. The cytocromes OmcB,OmcE,OmcS, and MacA are our priority since they are the major electron smugglers out of the cell. By isolating and placing these cytocromes, some of which are naturally occur in E.Coli,into bricks we hope to make the electical application possible in other bacterial species. |
Overall project
Optimization of electron shuffle to external surfaces such as anodes is a primary goal. Geobacter sulfurreducens happens to be our model bacteria due to its ability in nature to efficiently export electrons extracelluarly. E. coli can be the chassis for this experiment due to its genome already containing some key proteins in our preferred pathway. The proteins, such as extracellular pilin, MacA, and many other cytochromes, which E. coli does not have will be isolated from Geobacter sulfurreducens and introduced into E. coli to formulate the most optimal pathway for generating electronmotive force in a microbial fuel cell apparatus.
Some problems will be faced concerning plasmid engineering and the simple fact that Geobacter is anaerobic and E. coli is aerobic. Also, the role of Geobacter's pili in extracellular electron transfer is not clearly understood and could create a significant problem since e. coli does not have such pili. As a team, we will push in the right direction harder than an emf on the internal resistivity of a toroid. Many diverse team members will work in concert utilizing Missouri S&Tâs dominating Electrical, Chemical, and Biological Engineering undergraduates along with Biological Science masterminds.
