In an effort to fight pollution through the process of bioremediation, our team proposes to develop bacteria that will be highly effective in degrading Polychlorinated Biphenyls (PCBs) with a long term goal of being able to help clean Lake Hartwell, a major recreational area for people of all ages in the upstate of South Carolina. To accomplish this, we have adapted and expanded the model constructed by the 2011 UT Tokyo team. The focus of their project was to engineer a division of bacteria that would increase the efficiency of bioremediation in any given environment. Their two-component system is comprised of a cell assembling and a cell arrest system. Within the parameters of the cell assembling system, their employed mechanism was to use chemoattraction to increase the density of bacteria at a desired location. To accomplish this, aspartate was used as a natural chemoattractant, and its production was induced by the presence of the substrate. The cell arrest system, a secondary extension of system one, is used to maintain a high density of bacteria once they have reached the desired location since it is likely that the concentration of bacteria will dissipate as the substrate is degraded. This system operates by “arresting” or prohibiting the rotation of the flagellum by regulation of the cheZ gene and thereby decreasing cell motility. Following a few key modifications, such as a change in promoters, this system will be adjusted to work perfectly for our project.
