Nitrosomonas is a genus of Gram-negative bacteria that play a crucial role in the nitrogen cycle. These ubiquitous microorganisms are chemoautotrophs, meaning they obtain energy from the oxidation of inorganic compounds and use carbon dioxide as their carbon source. Specifically, Nitrosomonas species are responsible for the first step of nitrification, the oxidation of ammonia (NH3) to nitrite (NO2-). This process is essential for converting ammonia, which can be toxic to many organisms, into a less harmful form.

The genus Nitrosomonas contains several recognized species, including Nitrosomonas europaea, Nitrosomonas eutropha, and Nitrosomonas mobilis. They are commonly found in soil, freshwater, and marine environments, particularly in areas rich in ammonia, such as wastewater treatment plants, agricultural soils, and marine sediments. Their metabolic activity is vital for maintaining the balance of nitrogen in ecosystems, influencing plant growth and preventing the accumulation of toxic ammonia. The oxidation of ammonia by Nitrosomonas generates energy, which they use to fix carbon dioxide into organic molecules. This process is typically aerobic, requiring oxygen to proceed. The nitrite produced by Nitrosomonas is then further oxidized to nitrate by other bacteria, completing the nitrification process.
