Environment has been a track in iGEM for a long time. Projects that tackle issues surrounding

Winning Environment projects in 2013

Undergrad: TU-Munich (also first runner up at the World Championships)

Physco Filter

Project abstract: The contamination of aquatic ecosystems with multiple anthropogenic pollutants has become a problem since the industrial revolution. Antibiotics, hormones and various noxious substances threaten environmental health and are not effectively removed by conventional waste water treatment.

We propose to employ transgenic plants which produce effectors for enzymatic degradation (BioDegradation) or specific binding (BioAccumulation) of pollutants. The autotrophic, sedentary, aquatic nature of the moss Physcomitrella patens makes it an ideal chassis for a self-renewing, low-maintenance and cheap water filter. A light-triggered kill switch prevents unintended environmental spreading by limiting viability to places where the spectrum of sun light is appropriately filtered. Furthermore, we have developed a device to implement this biological filter in an aquatic environment, investigated the application of this new technology and examined its economic feasibility. Based on our results, PhyscoFilter may become a game-changing approach to improve global water quality in an affordable and sustainable fashion.

Overgrad: NYMU-Taipei

Bee. Coli

Project abstract: To save bees from Nosema ceranae, the culprit of colony collapse disorder (CCD), we created Bee. coli. from E. coli K-12 MG1655, a bacterium residing natively in bees. Bee. coli is strategically designed to work as follows. First, it continuously secretes mannosidase to inhibit the sprouting of N. ceranae spores. Second, if the bee is infected, the fungus-killing-circuit with a positive feedback design will be turned on to wipe out N. ceranae. Third, if these designer weapons should fail to conquer N. ceranae, our designed bee-suicide-operon will be activated to kill the infected bee and save its companions. Fourth, a light-inducible lysis system is included to ensure our Bee. coli only lives inside of the bee. Fifth, we apply encapsulation as the way to send Bee. coli into the bee. Since the capsule will only dissolve in a bee’s gut, our Bee. coli will not spread to the environment.
