        The public generally considers synthetic biology as an immoral concept, although if you imagine it as an episode of Scooby Doo, it doesn’t seem so bad; everyone is scared of this unknown monster, but underneath this mask is just a janitor. In the case of our project ToxiMop, we are using a ‘janitor bacterium’ to mop up the microcystin toxin from freshwater reservoirs!

          What comes to people's mind when they hear the term 'synthetic biology'? Many people don't know what it is, or have an ambiguous idea that it is something dangerous, potentially immoral. It can be thought of as playing with the universe's lego kit. Building with what is already here, naturally, biologists attempt to create better biological systems and machinery to advance life on earth. </p>

ToxiMop - Splash and the toxin's gone!

The Microcystin Monster

Algal blooms are an ever-growing problem in freshwater systems. At the Beijing Olympics 2008, 10,000 people were hired to clean up the extensive algal bloom in time for the sailing regatta. The main concern is the level of a toxin called microcystin, which is released by cyanobacteria when they die and lyse.

Microcystin, a toxin released by Microcystis aeruginosa, is harmful to mammals due to its ability to latch on to the human protein PP1, thus ceasing its operation. We are exploiting the ability of the human protein phosphatase (PP1) to covalently bind to microcystin, in order to develop a biological mop ‘janitor’ to rid algal bloom water of the toxin.


ToxiMop

Using B. subtilis and E. coli as chassis to express PP1. This will act as a molecular “mop”.

Detector

An electronic sensing device which detects and monitors the state of a freshwater system. It will allow us to predict the likelihood of algal blooms.

Moptopus

An electronic sensing device which detects and monitors the state of a freshwater system. It will allow us to predict the likelihood of algal blooms.

Human Practices

Current regulations of measuring water quality may not be appropriate. We organised a political campaign to ignite a nationwide debate.
