Overall project
The process of in situ Bioremediation would be aided through the use of microorganisms that undergo synchronized cell death. Bioremediation relies on microorganisms' enzymatic pathways to break down hazard chemicals in the environment. However, in order to protect the environment from the release of a foreign population of microorganisms, most contaminants have to be excavated or pumped off-site (ex situ) before the proper microogranisms can be applied. The transport of contaminants makes ex situ bioremediation just as expensive as the burn or bury methods of waste removal. Although if the remediating microorganisms were engineered to clean up until the contaminant was removed, and then collectively die, their impact on native populations could be reduced significantly.
To achieve synchronized apoptosis after a set number of generations we first had be able to count cell divisions with a GFP. The origin of replication, OriC, would have to be cloned out of E. coli, but to be functional, it would still need to retain the proper binding site spacing and restriction regions around the OriC promoter.
