Abstract

This research proposal aims to replacement of N2 molecule (instead of O2) as a final electron receptor in micro-organisms so that they can produce NH3, which is important industrially, instead of H2O. 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, NH3 is an expensive product because it is produced using Haber-Bosch reaction technique which requires high temperature and pressure. Therefore, it is predictable here to produce NH3 so simply in bioreactors which is a great economic benefit.
