Nitrosomonas
Nitrosomonas
Nitrosomonas (pronunciation: /naɪˌtroʊsoʊˈmoʊnəs/) is a genus of Gram-negative bacteria in the family Nitrosomonadaceae.
Etymology
The name Nitrosomonas is derived from the Greek words 'nitro' meaning nitrate and 'monas' meaning unit. This name is in reference to the bacteria's ability to oxidize ammonia into nitrite, a process known as nitrification.
Description
Nitrosomonas are rod-shaped bacteria that are typically 0.5-2.0 μm in length. They are chemoautotrophs, meaning they obtain energy from chemical reactions and use carbon dioxide as their primary source of carbon. Nitrosomonas are known for their role in the nitrogen cycle, where they convert ammonia into nitrite, a process known as ammonia oxidation.
