For the Integrated Human Practices, our team searched through the iGEM registry for a possible kill switch for our microbe. A kill switch would be useful so that people would feel more comfortable ingesting the capsule or putting it in water they will later drink. A kill switch would allow the bacteria to be shut down or limited to make sure the population does not grow uncontrolled. We also looked for parts the might improve our project to help people from getting sick from other harmful bacteria and molecules.Two parts were found that we could use in continuation projects in the next few years. These parts are a population capping device and a dCBD improvement that can bind to metals.
This part is a growth inhibition device makes a cell release BMP2 that can slow or stop the growth of bacteria. In the future, this part can be modified to keep the cell population of our E. coli controlled in the colon of humans or in water. It would allow the cells to not grow and overtake the cells that are already living in the ecosystem. This part is already modified for cells in the colon and could be a great addition to our E. coli.
