Project Overview

In the 2013 competition the TU Munich iGEM team has developed a transgenic moss filter which is capable to reduct the the contamination of aquatic ecosystems with xenobiotics. The topic of remediation using transgenic organisms is present in every year of iGEM and we want to take this idea to the next level. For this reason we decided to use a photoautotrophic chassis which we enabled for the iGEM competition. The following section gives an overview over the theoretic background of our project.


Phytoremediation

Figure 1:

Phytoremediation describes the treatment of environmental problems through the use of plants. Here we identified problematic substances and described basic principles (Read more).

PHyscomitrella

Figure 2:

As next point we introduce Physcomitrella patens as a nearly new chassis to iGEM. We describe advantages and possiblilities and describe our expression strategy (Read more).

Localisation

Figure 3:

As the principle of action for the effectors responsible for the Phytoremediation are very different it is necessary to have a expression system which is able to accomplish cytosolic, secreted, receptor bound localisation of proteins (Read more).

BioDegradation

Figure 4:

BioDegradation describes the application of enzymatic catalysis for the degradation of problematic xenobiotics using an erythromycin esterase, a catechol dioxigenase and a laccase (Read more).


Safety

Figure 5:

Our safety page describes our teams discussion concerning safty issues, especially a safety evaluation of our BioBricks and Physcomitralla including all constructed GM-plants (Read more).

Kill-switch

Figure 6:

In order to restrict the growth of transgenic moss to a controlled environment we developed a kill-switch which becomes triggered by sunlight. The GM-moss can only be grown in places where redlight has been filtered out (Read more).
