Equipment for a study of nitrogen fixation by alpha rays (Fixed Nitrogen Research Laboratory, 1926)
This high-pressure reactor was built in 1921 by BASF in Ludwigshafen and was re-erected on the premises of the University of Karlsruhe in Germany.
Louis Pasteur showed that Spallanzani's findings held even if air could enter through a filter that kept particles out.

Ammonia occurs in the atmospheres of the outer giant planets such as Jupiter (0.026% ammonia), Saturn (0.012% ammonia), and in the atmospheres and ices of Uranus and Neptune.

Nitrogen fixation is a chemical process by which molecular nitrogen, with a strong triple covalent bond, in the air is converted into ammonia or related nitrogenous compounds, typically in soil or aquatic systems but also in industry.

- Nitrogen fixation

Nitrogen fixation is carried out naturally in soil by microorganisms termed diazotrophs that include bacteria, such as Azotobacter, and archaea.

- Nitrogen fixation

He was responsible for the first isolation and description of both nitrifying and nitrogen-fixing bacteria.

- Microorganism

These organisms are also common in soil and play a vital role in ammonia oxidation.

- Microorganism

Anhydrous ammonia is currently used commercially to reduce or eliminate microbial contamination of beef.

- Ammonia

Therefore, nitrogen fixation is required for the synthesis of amino acids, which are the building blocks of protein.
