Using N2 as a final electron receptor in yeast to produce NH3 in bioreactors

This research proposal aims for the replacement of N 2 molecule (instead of O 2 ) as a final electron receptor in micro-organisms so that they can produce NH 3 , which is important industrially, instead of H 2 O. This idea is based on the hypothesis that replacement of the central atom in gas-carrying compounds in living organisms such as chlorophyll, heme and hemocyanin would replace the fixed gas. However, NH 3 is an expensive product because it is produced using the Haber-Bosch reaction technique which requires high temperature and pressure. Therefore, it is predictable here to produce NH 3 so simply in bioreactors which is a great economic benefit.
