April nanoTalks: Sustainability & Microbes
Talk 1: The Promise of Synthetic Biology
Presented by Alexander Schanne, Bsc. Biology at University of Zurich & President of SynBio UZH
Since the industrial revolution our society has made enormous technological advances. While improving the livelihood of millions of people, these advancements also came with the cost of rising CO2 levels and pollution among many others. Countless production processes, especially fuel production, have to be rethought to be fully sustainable to prevent worst case scenarios of climate change. Synthetic Biology, which applies engineering principles on biological organisms provides a solution to invent closed cycles for the production of fuel, plastic and other, currently unsustainable products.
Talk 2: Biological Nitrogen Fixation for Food Security
Presented by Carolin Schulte, PhD Candidate, Department of Engineering Science, University of Oxford
With the global population predicted to reach 11 billion by 2100 and the area of arable land decreasing due to global warming, there is an urgent need for agricultural practices that achieve high yields in a sustainable way. Nitrogen, despite being the major component of the air we breathe, is commonly one of the most limiting nutrients for plant growth. While humans have circumvented this problem with the application of fertilisers, nature has come up with its own solution for making nitrogen available to plants, with soil bacteria «fixing» atmospheric nitrogen directly inside the plant root. This talk will explain the science behind biological nitrogen fixation and discuss opportunities and limitations of this approach for ensuring global food security.
