Key Physiology of Anaerobic Ammonium Oxidation
The physiology of anaerobic ammonium oxidizing (anammox) aggregates grown in a sequencing batch reactor was investigated quantitatively and the anammox process was completely inhibited by nitrite concentrations higher than 0.1 g of nitrogen per liter.
Anaerobic ammonium oxidation by anammox bacteria in the Black Sea
Evidence for bacteria that anaerobically oxidize ammonium with nitrite to N2 in the world's largest anoxic basin, the Black Sea is provided and anammox bacteria have been identified and directly linked to the removal of fixed inorganic nitrogen in the environment.
Completely autotrophic nitrogen removal over nitrite in one single reactor.

It was shown that the Anammox process was inhibited reversibly by the presence of oxygen, and aerobic nitrifiers were shown not to play an important role in the Anamox process.
Biomarkers for In Situ Detection of Anaerobic Ammonium-Oxidizing (Anammox) Bacteria
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”.

It appeared that, under carbon-and energy-limited conditions, a high nitrification rate was correlated with a reduced biomass yield, and several species considered to be "poor" nitrifiers also simultaneously nitrify and denitrify, thus giving a falsely low nitrification potential.
Sewage Treatment with Anammox
This work explores process innovations that can speed up the anammox process and use all organic matter as much as possible for energy generation.
Oxidation of reduced inorganic sulphur compounds by acidophilic thiobacilli.
Thiobacillus ferrooxidans is widely used as a model organism to study the biological oxidation of pyrite and is an obligately chemolithoautotrophic, aerobic bacterium.

The results suggest that ferric iron may be an important electron acceptor for the oxidation of sulfur compounds in acidic environments.
