UPWr students received a medal for air purification
Students of the University of Environmental and Life Sciences in Wroclaw returned from the USA with a bronze iGEM medal for microbiological filters from yeast which clean air from heavy metals.
According to the European Environment Agency (EEA), Poland is one of the largest heavy metal emitters, and excess lead, cadmium or mercury in the air have severe health effects. UPWr students have invented biological filters based on modified Yarrowia lipolytica yeast, which absorb heavy metals and signal their excessive concentration by turning red and giving off a peach odour.
Although attempts have already been made to purify water or soil with the use of yeast, there are still no filters on the global market that use microorganisms to purify the air. Research on such a filter can be a breakthrough in monitoring and combating high concentrations of heavy metals in the air. Students working under the supervision of prof. Zbigniew Lazar have already created a prototype heavy metal sensor, suitable for use in flats. Now the project is entering the phase of creating a filter that will catch out and neutralize harmful substances in the air. It could be installed in, for example, ventilation grates – the air flow would ensure their cleaning.
The importance of microbiological filters for improving the quality of life in the industrialized parts of the world and for combating pollution has been confirmed by a bronze medal that UPWr students brought from Boston. They obtained the funding for the trip from the Ministry of Science and Higher Education – a grant from the "The best of the best!" programme, promoting students’ travel abroad.
The International Genetically Engineered Machine (iGEM) is an international competition in synthetic biology that takes place every year in Boston. Organized by the Massachusetts Institute of Technology (MIT), it is one of the most prestigious events for students of biological and engineering sciences. The idea of the competition is to present innovative projects prepared by students from around the world, which use the tools of modern synthetic biology – a discipline combining molecular biology and engineering which creates artificial biological systems modelled on natural ones.
About 300 teams participate in the competition every year. This year's 12-people team from UPWr was the only team from Poland and the first ever from Wrocław. It consisted of 9 students from three research clubs: SKN (Student Research Club) Bioinformatics, SKN Biotechnologists and SKN OrgChem – as well as three scientific supervisors. Here they are:
