Design Notes

First of all, our engineered microorganism will be applied to farmland, in order to prevent possible escape of engineered microorganism, the use of conditional kill switches is not necessarily a good way, because the triggering conditions in the field environment are very uncertain, which greatly increases the possibility of escape of engineered microorganism. Therefore, we conceived this auto-timing kill switch, hoping that the engineered microorganism can commit suicide at a certain time to prevent the escape. However, because Trichoderma atroviride is not a typical model organism, it lacks clearly characterized components, which is also a common problem faced by teams who want to develop new chassis, so we use the classical model organism Escherichia coli as our chassis bacteria. Because of the long experimental period, we plan to use modeling to characterize our auto-timing kill switch.


Source

The improved version of the effector is independently designed by SZU-China.
