First Meet Up of the Greek iGEM teams

iGEM Thessaly: The research team from the University of Thessaly organized the First Meet Up of all the Greek iGEM teams at the city of Larissa on Saturday 13 July.

The students of the iGEM Thessaly team conducted from 12 to 14 of July a meeting with the Greek teams iGEM Athens and Thessaloniki that are also taking part in the iGEM competition this year at the city of Larissa, Thessaly. 

iGEM is an international completion taking place in Boston on October. It started in 2004 at MIT with only a few teams participating, exclusively from the United States. Today, there are more than 300 teams competing from all over the world. 

One of iGEM’s main goals is to promote collaboration among the iGEM teams and, as an extension, to society. In this context, iGEM Thessaly hosted the First Greek Meet Up and invited iGEM Athens and Thessaloniki to Larissa. The aim of this meet-up was for every team to present their project to the rest and receive useful feedback, comments, and ideas. The conference that was held on Saturday 13th of July.Apart from the teams’ presentations, an iGEM Alumni panel (consisting of exceptional guests with great experience in the iGEM competition) initiated  a constructive discussion with and filled a lot of gaps for the students that are making their first attempt to participate in something this big.

The conference was enriched by interesting talks by postdoctoral researchers of the Department of Biochemistry and Biotechnology. The invited speakers  were Constantine Garagounis, from the Laboratory of Plant and Environmental Biotechnology, and Konstantina Tsoumani , from the Laboratory of Molecular Biology and Genomics., We were also happy to host the coordinator of Academia and Research Committee of After iGEM Thea Chrysostomou, the iGEM Sheffield supervisor Dimitris Michailidis, and Giannis Ntekas, iGEM Athens 2018 team leader. Finally,  it was a great honor that our PI Papadopoulou Kalliope, who has been supporting as from the beginning, attended our meet up. 

We wish good luck to all the Greek iGEM teams!

iGEM Aachen 2019: Plastractor

Currently everybody talks about environmental pollution by plastic. But not only big plastic waste, like plastic bottles, are a problem for us, but also microplastic, which e.g. was found in drinking water. Microplastics, particles smaller than 5mm, generated by degradation via wave motion and UV radiation, can work their way into the marine food chain and eventually into the human body.

With our project, we want to approach the microplastic problem. On the one hand we want to produce an easy way to detect micro- and nanoplastics in fluids and differ between different polymers. On the other hand, our project should create an easy way to extract them. Magnetic purification seemed to fit, as it doesn’t require any chemicals or elevated equipment.

Currently there are known magnetic bacteria existing, e.g. Magnetpospirillum gryphiswaldense, which thrive in the sediments of freshwater streams or marine sediments in very low oxygen environments. The most fascinating ability of these bacteria is their capability to produce so called magnetosomes, spherical vesicle-like structures of membrane-coated, biomineralized ferrite monocrystals with an approximate diameter of 45 nm. These are aligned by special cytoskeletal proteins inside the cell body to form little compass needles, which allow the bacteria to orient themselves along the earth’s magnetic field.

We want to develop novel fusion proteins embedded into the vesicular membrane of magnetosomes being able to specifically bind certain polymers, for example polypropylene (PP). They are consisting of a transmembrane domain as well as a variable linker domain and a domain for binding the polymer.

Novel fusion proteins embedded into the vesicular membrane of magnetosomes can be developed, able to specifically bind certain polymers, for example polypropylene (PP). For detection purposes there is a fluorescent protein marker inside the fusion protein that marks the polymer particle for fluorescent detection.

Our project aims to make the world a little less “plastic”. We don’t want to build up new plastic but to remove the one already present.

You can ask us anything via e-mail (igem@rwth-aachen.de) and also follow us on Facebook, Instagram and Twitter to stay in touch with us and our journey to the competition in October.
