Missing lithotroph identified as new planctomycete
With the increased use of chemical fertilizers in agriculture, many densely populated countries face environmental problems associated with high ammonia emissions. The process of anaerobic ammoniaExpand

A microbial consortium couples anaerobic methane oxidation to denitrification
Modern agriculture has accelerated biological methane and nitrogen cycling on a global scale. Freshwater sediments often receive increased downward fluxes of nitrate from agricultural runoff andExpand

Nitrite-driven anaerobic methane oxidation by oxygenic bacteria
Only three biological pathways are known to produce oxygen: photosynthesis, chlorate respiration and the detoxification of reactive oxygen species. Here we present evidence for a fourth pathway,Expand

Anaerobic ammonium oxidation by anammox bacteria in the Black Sea
The availability of fixed inorganic nitrogen (nitrate, nitrite and ammonium) limits primary productivity in many oceanic regions. The conversion of nitrate to N2 by heterotrophic bacteriaExpand

Deciphering the evolution and metabolism of an anammox bacterium from a community genome
Anaerobic ammonium oxidation (anammox) has become a main focus in oceanography and wastewater treatment. It is also the nitrogen cycle's major remaining biochemical enigma. Among its features, theExpand

Molecular mechanism of anaerobic ammonium oxidation
Two distinct microbial processes, denitrification and anaerobic ammonium oxidation (anammox), are responsible for the release of fixed nitrogen as dinitrogen gas (N2) to the atmosphere.Expand

Biochemistry and molecular biology of anammox bacteria
Anaerobic ammonium-oxidizing (anammox) bacteria are one of the latest additions to the biogeochemical nitrogen cycle. These bacteria derive their energy for growth from the conversion of ammonium andExpand

A microdiversity study of anammox bacteria reveals a novel Candidatus Scalindua phylotype in marine oxygen minimum zones.
The anaerobic oxidation of ammonium (anammox) contributes significantly to the global loss of fixed nitrogen and is carried out by a deep branching monophyletic group of bacteria within the phylumExpand

Biomarkers for In Situ Detection of Anaerobic Ammonium-Oxidizing (Anammox) Bacteria
The existence of anaerobic ammonium oxidation (anammox) was hypothesized based on nutrient profiles and thermodynamic calculations (5, 31, 44). It was first discovered about 1 decade ago (25) in aExpand

Methanotrophic symbionts provide carbon for photosynthesis in peat bogs
Wetlands are the largest natural source of atmospheric methane, the second most important greenhouse gas. Methane flux to the atmosphere depends strongly on the climate; however, by far the largestExpand
