Stony-Brook # Nitroscillator: Engineering Sustainable Nitrogen-Fixing Bacteria with Genetic Oscillators # Nitrogen fertilizers are used to fulfill the food requirements of a growing, global population. However, due to the environmental repercussions of fertilizer synthesis and usage, an alternative is needed. We propose a sustainable biofertilizer design that replicates diazotrophs’ nitrogen-fixing ability while reducing environmental impact. Our approach involves introducing nitrogenase genes into an oscillatory genetic network in Escherichia coli and Pseudomonas protegens.

The-Kings-School-AU # Solutions for our Soil — Engineering Nitrogen Fixing Bacteria with Oxygen Sensing Capabilities # The overuse of synthetic nitrogen-based fertilisers has caused significant damage to ecosystems across the globe. Our project aims to use synthetic biology to engineer E. coli to produce ammonia naturally, in order to decrease the fossil fuels and nitrogen pollution impact of the fertiliser industry. SOILutions aims to develop an oxygen-sensing feature that allows the bacteria to activate only under low oxygen conditions, increasing the longevity and usability of these engineered microorganisms.
