Nitrifying bacteria use ammonia/ammonium and nitrite as an electron donor and oxygen as a final electron acceptor [29] thus the oxygen presence becomes one of the prerequisites for an optimum growth of nitrifying bacteria.
Interestingly, nitrifying microbes exposed in vitro to low concentrations of a metal can develop a tolerance to the metal and even resist future exposures of high, normally inhibitory concentrations (Mertoglu et al.
1]; in non-renewal water concentrations are very low and show the absorption of this element by the phytoplankton and the activities of nitrifying bacteria in the environment (SIPAUBA-TAVARES et al.
1, 2006 Environmental Science & Technology, the researchers reported that slow-growing microbes called nitrifying bacteria, which convert ammonia to nitrate, can also degrade those two pharmaceuticals.
He spent four years working on nitrifying bacteria before Watson persuaded Roger Stanier at the University of California, Berkeley, to take him on as a graduate student.
Nitrification seems to be nearly totally absent, probably because of the high organic carbon levels in the water which leads to the dominance of heterotrophic bacteria and suppresses the development of nitrifying organisms (Table 4).
