Realizing a Light-Inducible Kill Switch

T--Kingsborough NY--phantom1.jpg

Organisms engineered by synthetic biologists have the potential to deliver new solutions to a wide range of problems. However, they must be implemented in responsible and controlled ways.

For example, last year the Kingsborough team focused on engineering E. coli, to deteriorate nitrogenous waste in sewage more effectively. However, we found that E. coli can survive in local waterways, which is the ultimate destination for wastewater after treatment. To prevent the escape of our organism, and develop this idea further, we are focused this year on improving and characterizing a control element, commonly referred to as a "Kill Switch." With this kill switch, we will be able to combat the escape of modified E. coli from the treatment plant.

We focused on the development of a light-inducible kill switch; since the bacteria will not be exposed to significant amounts of light within the sewage treatment plant. Other teams have proposed and modeled such switches, but few have successfully built, implemented, and characterized such devices. We will be building upon our past design, as well as improving and completing a previously proposed light-inducible kill switch (in particular, the design of team Wageningen from 2016).

Thus, the bacteria would create would hopefully be creatures of the night - not unlike the famous Phantom of the Opera!
