Also, some nitrification will take place due to continues flush out of
nitrifying biomass from the trickling filters, which then accumulates in the activated sludge and will cause some nitrification in the aerated zones of the aeration tanks.
Three different types of plastic pieces were used as media for
nitrifying bacteria growth.
Thus, the bio-filter was proven to be efficient enough to provide appropriate surface area for
nitrifying bacteria to colonize and populate.
by pelagic
nitrifying bacteria, hence explaining their observation of elevated N[O.
The reason why there still some microbial activity was inhibited at the height of 10cm was that organic matter concentration of wastewater quality in experiment was lower so that there was phenomenon of a certain
nitrifying bacteria existing of inflow and there was not condition of heterotrophic bacteria and autotrophic bacteria stratifying; while as the increasing of the height of the sampling connection, the inhibition ratio of hydrolyzing urea increased gradually.
High concentrations of ammonium ion in the well waters had resulted in the colonization of the distribution system with
nitrifying bacteria which mediated the conversion of ammonium to nitrite ion.

nitrifying organisms, and enzyme activities in a rice-oilseed rape cropping system.
Allison SM, Prosser JI (1993) Ammonia oxidation at low pH by attached populations of
nitrifying bacteria.
5 (Burton and Prosser 2001), and Alexander (1977) stated that numbers of
nitrifying bacteria and nitrification activity in soil decline markedly below pH 6.
Martens-Habbena W, Berube PM, Urakawa H, de la Torre JR, Stahl DA (2009) Ammonia oxidation kinetics determine niche separation of
nitrifying Archaea and Bacteria.
These include removal by
nitrifying bacteria and seaweeds (Losordo et al.
The
nitrifying process in a microorganism takes place in two phases: 1) oxidation of ammonium to nitrite, and 2) oxidation of the nitrite to nitrate.
