Systems and methods for producing ammonia are described. In one embodiment, hydrogen, carbon dioxide, and nitrogen are dissolved in a solution. A glutamine synthetase inhibitor and autotrophic diazotroph bacteria are also placed in the solution.

Ammonia synthesis methods and systems

Systems and methods for fixing carbon using bacteria are described. In one embodiment, a system includes a reactor chamber with a solution contained therein. The solution may include hydrogen (H), carbon dioxide (CO), bioavailable nitrogen, and a chemolithoautotrophic bacteria. The system may also include a pair of electrodes that split water contained within the solution to form the hydrogen. Additionally, the system may be operated so that a concentration of the bioavailable nitrogen in the solution is below a threshold nitrogen concentration to cause the chemolithoautotrophic bacteria to produce a product.
