Nitrifying bacteria are chemolithotrophic organisms that include species of genera such as Nitrosomonas, Nitrosococcus, Nitrobacter, Nitrospina, Nitrospira and Nitrococcus. These bacteria get their energy from the oxidation of inorganic nitrogen compounds . [ 1 ]
Nitrification can also occur in drinking water. In distribution systems where chloramines are used as the secondary disinfectant, the presence of free ammonia can act as a substrate for ammonia-oxidizing microorganisms. The associated reactions can lead to the depletion of the disinfectant residual in the system. [33]
Comammox have been found in many engineered systems including aquaculture biofiltration units, drinking water treatment and distribution systems, and wastewater treatment plants. [ 3 ] [ 6 ] The growth of comammox in these engineered ecosystems co-occur with ammonia-oxidizing bacteria and/or archaea, and in some cases outnumber other ammonia ...
Elevated nitrate in groundwater is a concern for drinking water use because nitrate can interfere with blood-oxygen levels in infants and cause methemoglobinemia or blue-baby syndrome. [28] Where groundwater recharges stream flow, nitrate-enriched groundwater can contribute to eutrophication , a process that leads to high algal population and ...
Ever since nitrifying bacteria were discovered it was accepted that nitrification occurred in two steps, although it would be energetically favourable for one organism to do both steps. [19] Recently Nitrospira members with the abilities to perform complete nitrification ( comammox bacteria) have also been discovered [ 9 ] [ 12 ] [ 20 ] and ...
Nitrifying bacteria have an optimum growth between 77 and 86 °F (25 and 30 °C), and cannot survive past the upper limit of 120 °F (49 °C) or the lower limit of 32 °F (0 °C). [1] This limits their distribution even though they can be found in a wide variety of habitats. [1]
Purple and green bacteria oxidize sulfide, sulfur, sulfite, iron or hydrogen. Cyanobacteria and plants extract reducing equivalents from water, i.e., they oxidize water to oxygen. The electrons obtained from the electron donors are not used for ATP production (as long as there is light); they are used in biosynthetic reactions.
Nitrosomonas is a genus of Gram-negative bacteria, belonging to the Betaproteobacteria.It is one of the five genera of ammonia-oxidizing bacteria [8] and, as an obligate chemolithoautotroph, [9] uses ammonia as an energy source and carbon dioxide as a carbon source in the presence of oxygen.
