Our project

Synthetic biology is defined as the design and fabrication of biological components and systems that don’t exist in a natural environment. It’s also the redesign and fabrication of existing biological systems. (1) This is exactly what we did in our project. We used components of different organisms and put these together to make our own designed organism. For example, we used a couple of receptors from Agrobacterium tumefaciens for the vanillin detection. This means that we created an organism that normally doesn’t exist in nature. It’s important to notice that this can have a major effect on the environment if the organism is released. It can become stronger than other similar and natural organisms and eventually displace all endogenous organisms. Our organism is designed in such a way that it can only exist if it receives the proper nutrients. When it is released in a natural environment, it’s to weak to survive. Therefore we didn’t add a dead-man-switch to the design. The bacterium can grow untill the nutrients are consumed and then they just die. A second reason to leave the dead-man-switch out of the design is the fact that this organism doesn’t interfere with humans or other organisms. In our project the bacteria remain safely in a container and in other applications they are kept in the laboratory where it’s used (e.g. bioreactor). A third argument that made us decide that the dead-man-switch wasn’t necessary is the fact that the strain of Escherichia coli we used can’t do any harm to people and is to weak compared to other organisms. All these things and the purpose of our project make it possible to minimize the risks of modifying organisms.
