Problem

The iGEM team of the Eindhoven University of Technology sees high potential in the usage of genetically modified bacteria as innovative solutions in a wide range of fields such as energy, health and the environment. However, the actual application of the micro-organisms often does not only give rise to regulatory issues, but also to issues concerning the resilience of these bacteria. For example, the application of bacteria in clinical settings - for instance as drug delivery systems in cancer therapies [1] or as devices for local production of contrast agents for MRI visualization (TU Eindhoven 2013 iGEM team) - is not that straightforward, since the human immune system will neutralize and eventually remove the bacteria. Also, the bioreactor industry would greatly benefit from more resilient bacteria. The efficiency of these bioreactors would increase, if the bacteria are able to survive under higher pressures and temperatures (Figure 1). Moreover, in numerous iGEM projects actual application of the bacteria in the intended way, would result in inactivation or removal before the bacteria can fulfill its engineered purpose. For these reason, the iGEM project of team TU Eindhoven 2014 focuses on the limited ability of genetically engineered bacteria to survive under non-natural conditions, since this is a fundamental problem in their future application. Therefore, the aim is to develop and characterize a universal tool, which could be a starting point for a solution to this fundamental problem.
