The excessive use of disposable plastic and the lack of universal recycling programs has led to the [http://www.ncbi.nlm.nih.gov/pubmed/22610295 pollution of the world's oceans]. In the ocean, large pieces of Polystyrene litter are ground by sea currents and degraded by UV radiation into very small pieces, so called "plastic plankton," which is consumed by fish, filter feeders, and other marine organisms. Such plastic uptake can lead to poisoning, sterility and death. The [http://partsregistry.org/wiki/index.php/Part:BBa_I728500 CPX-peptide], created by the 2007 MIT iGEM team, can bind to Polystyrene. CPX-'''Sporo'''beads in huge filter boxes could be put into place to mechanically filter microscopic plastic particles, like Polystyrene microparticles, out of the water. Such specific filtration would be superior to blanket filtration systems, which also remove living phytoplankton important to ocean ecosystems. To prevent the beads from being released into the sea and to ensure the plastic be removed from the water, the '''Sporo'''beads could be attached to membranes in the filter boxes. Then the '''Sporo'''beads would need to not only display CPX but also a membrane binding protein on their surface.

Since the 1990s, green biotechnology has released 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 our '''Sporo'''beads are stable and safe vehicles, they could be sent by mail without any extra security precautions. 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".
