The excessive use of disposable plastic and the lack of universal recycling programs has led to the pollution of the world's oceans. In the ocean, large pieces of Polystyrene litter are ground by sea currents into very small pieces, so called plastic plancton, that are consumed by fish, filter feeders, and other organisms living in the oceans. Such plastic uptake can lead to poisoning, sterility and death. The [http://partsregistry.org/wiki/index.php/Part:BBa_I728500 CPX-peptide] can bind to Polystyrene and was generated by the iGEM team from MIT (2007). CPX-'''Sporo'''beads in huge filter boxes could be put into place to mechanically filter microscopic plastic particles, like polystyrene plancton, out of the water. To prevent the beads from being released into the sea and the plastic to be kept, the '''Sporo'''beads could be attached to membranes in the boxes. Then the '''Sporo'''beads would need to not only display CPX but also a membrane binding protein on their surface. [security]

Since 1990, green biotechnology releases many transgenic plants into the environment by selling genetically modified seeds. Thus, organic farmers need to prove that their products meet the requirements for organic crops. Usually they pay laboratories to attest the lack of contamination with genetically modified crops. New tools for sequence-specific DNA-binding of molecular biology, TAL effectors, combined with our '''Sporo'''beads could be an easy and cheap solution for organic agriculture. Farmers could use a kit with TALE-''lacZ''-'''Sporo'''beads to detect sequences specific for GM-crops. As spores are stable and safe vehicles, they could be send by mail without any considerations. The kit would be suitable for use outside of laboratory. The protocol for this could work as follows:
 
-
<br>DNA extracted from plants with solutions provided by the kit is immobilized and fixed on a nitrocellulose membrane. This membrane is then washed, incubated with '''Sporo'''beads in solution and washed again. With addition of a substrate, the surface displayed LacZ of bound '''Sporo'''beads will catalyze a reaction so that a blue staining appears. If no such DNA is present, the spores will not bind and no blue color will appear.</p>

iGEM Ludwig-Maximilians-Universität München Beadzillus

Team-LMU Photo2.jpg

The LMU-Munich team is exuberantly happy about the great success at the World Championship Jamboree in Boston. Our project Beadzillus finished 4th and won the prize for the "Best Wiki" (with Slovenia) and "Best New Application Project".
