Cockroach is one of the pests we often see in our house. Usually, we use a pesticide to kill them. However, commercially available pesticides contain harmful chemical compounds for environment and even for human. Therefore, we will produce safe and harmless chemical compounds to kill cockroach using E. coli.

In our projects, we produce 3,3 diketotrehalose, which is a trehalase inhibitor. Cockroaches produce energy to live from trehalose by producing glucose from trehalose. To produce glucose form trehalose, cockroaches utilize an enzyme named trehalase. Therefore, inhibition of trehalase activity will result in death of cockroaches.

Our E. coli producing trehalase inhibitor will kill cockroaches without doing harm environment or human!

Exterminator coli: an engineered E. coli to safely eradicate roaches


Many pesticides use neurotoxins that show toxicity not only to insects but also towards other species, including mammals. We therefore set out to construct an E. coli that can safely eradicate cockroaches but not affect mammals.

Cockroaches and many other insects store their energy in the form of trehalose and use the enzyme trehalase to convert it to glucose when needed. Our engineered E. coli will overexpress the enzymes OtsA and OtsB to produce trehalose, and glucose-3-dehydrogenase to convert trehalose to 3,3’-diketotrehalose, an inhibitor of trehalase that is not toxic for mammals. Our engineered Exterminator coli will help eradicate roaches from homes without harming humans or pets.
