Future Directions

Our work with creating a system of inducible electrical output in Shewanella has laid the foundations for many different exciting avenues of further inquiry.

Using the same principles underlying the lac system, the arsenic system developed by the University of Edinburgh iGEM 2006 team could be introduced into Shewanella, allowing for the coupling of arsenic sensing to an electrical output, a form of a data which is easier to automate and transmit. This could be further extended to other chemical sensing systems, resulting ultimately in an array of different strains Shewanella which all respond to the presence of different chemicals with an electrical output that can be monitored by a computer. This could theoretically allow for the remote sensing and analysis of the chemical composition of an environment over time.
