"' Nitrosomonas communis "'is a ammonia-oxidizing, gram-negative, bacterium from the genus of Nitrosomonas which was isolated from the rhizoplane of the reed ( Phragmites communis ) from a wastewater treatment plant.

The reaction catalysed by these bacteria is the first step in the oxidation of ammonia to nitrate . " Nitrosomonas europaea " are also important in the treatment of industrial and sewage waste in the first step of oxidizing ammonia to nitrate.
34.
The nitrogen cycle is completed as follows : ammonia in the wastewater is converted to ammonium ions; the aerobic bacterium " Nitrosomonas " sp . oxidizes ammonium to nitrite; the bacterium " Nitrobacter " sp . then converts nitrite to nitrate.
35.
In 1888, he relocated to Zurich, where he began investigation into the process of nitrification, identifying the genera " Nitrosomonas " and " Nitrosococcus ", which oxidizes ammonium to nitrite, and " Nitrobacter ", which oxidizes nitrite to nitrate.
36.
Evidence suggests that ammonia-oxidizing bacteria contribute significantly to the global production of nitrous oxide ( produced by the reduction of nitrite ) . " Nitrosomonas europaea " is also capable of degrading benzene as well as a variety of halogenated organic compounds, including trichloroethylene and vinyl chloride.
37.
Nitrate formation by nitrite oxidising bacteria ( NOB ) ( such as " Nitrobacter " ) is prevented by adjusting temperature, pH, and retention time to select for nitr " i " fying ammonia oxidising bacteria ( AOB ) ( such as " Nitrosomonas " ).
38.
Nitrification is actually the net result of two distinct processes : oxidation of ammonia to nitrite ( ) by nitrosifying bacteria ( e . g . " Nitrosomonas " ) and oxidation of nitrite to nitrate by the nitrite-oxidizing bacteria ( e . g . " Nitrobacter " ).

;Lithoautotroph : An organism ( usually bacteria ) whose sole source of carbon is carbon dioxide and exergonic inorganic oxidation ( chemolithotrophs ) such as " Nitrosomonas europaea "; these organisms are capable of deriving energy from reduced mineral compounds like pyrites, and are active in geochemical cycling and the weathering of parent bedrock to form soil

Among the soil bacteria known to carry urease, some ammonia-oxidizing bacteria ( AOB ), such as species of Nitrosomonas, can also assimilate the carbon dioxide the reaction releases to make biomass via the Calvin Cycle, and harvest energy by oxidizing ammonia ( the other product of urease ) to nitrite, a process termed nitrification.
