TL;DR: These processes target the removal of ammonia from gases, and ammonium-bicarbonate from concentrated wastewaters (i.e. sludge liquor and landfill leachate) and the microbiology, its consequences for their application, the current status regarding application, and the future developments are addressed.

TL;DR: It was shown that propionate was oxidized mainly to CO2, with nitrate and/or nitrite as the electron acceptor, and that anammox bacteria have a more versatile metabolism than previously assumed.

TL;DR: Under anoxic conditions, pure cultures of N. eutropha were able to denitrify with molecular hydrogen as electron donor and nitrite as the only electron acceptor in a sulfide-reduced complex medium, and the increase of cell numbers was directly coupled to nitrite reduction.

TL;DR: Molecular techniques showed the presence of organisms affiliated with the anammox branch within the Planctomycetes in all these wastewater treatment plants, and 16S rRNA gene analysis, fluorescence in situ hybridization (FISH), and tracer experiments with [15N]ammonia showed the link between theAnammox reaction and the occurrence of theanammox bacterium “Candidatus Scalindua sorokinii”.

TL;DR: Nitrosomonas eutropha, an obligately lithoautotrophic bacterium, was able to nitrify and denitrify simultaneously under anoxic conditions when gaseous nitrogen dioxide (NO2) was supplemented to the atmosphere.
