Phanerozoic radiation of ammonia oxidizing bacteria. [PDF]
Sci Rep, 2021 The modern nitrogen cycle consists of a web of microbially mediated redox transformations. Among the most crucial reactions in this cycle is the oxidation of ammonia to nitrite, an obligately aerobic process performed by a limited number of lineages of ...

Dating Ammonia-Oxidizing Bacteria with Abundant Eukaryotic Fossils. [PDF]
Mol Biol EvolAbstract Evolution of a complete nitrogen cycle relies on the onset of ammonia oxidation, which aerobically converts ammonia to nitrogen oxides. However, accurate estimation of the antiquity of ammonia-oxidizing bacteria (AOB) remains challenging because AOB-specific fossils are absent and bacterial fossils amenable to calibrate ...

A review of ammonia-oxidizing bacteria and archaea in Chinese soils [PDF]
Frontiers in Microbiology, 2012 Ammonia (NH3) oxidation, the first and rate-limiting step of nitrification, is a key step in the global Nitrogen (N) cycle. Major advances have been made in recent years in our knowledge and understanding of the microbial communities involved ammonia ...

Comparison of enumeration methods for ammonia-oxidizing bacteria
Water Science and Technology, 2001 MPN, antibody, fluorescent in situ hybridization (FISH) and dot blot hybridization methods for enumeration of ammonia-oxidizing bacteria were applied to various samples from suspended systems. As for FISH, reoptimization of an oligonucleotide probe Nso190 was attempted. The advantages and disadvantages of these methods were discussed.

Biogeography of anaerobic ammonia-oxidizing (anammox) bacteria [PDF]
Frontiers in Microbiology, 2014 Anaerobic ammonia-oxidizing (anammox) bacteria are able to oxidize ammonia and reduce nitrite to produce N2 gas. After being discovered in a wastewater treatment plant (WWTP), anammox bacteria were subsequently characterized in natural environments ...

Metagenomic and cultivation-based description of a syntrophic butyrate-oxidizing bacterium from a thermophilic and high-ammonia biogas process. [PDF]
BMC MicrobiolBackground Ammonia inhibition in anaerobic digestion can lead to butyrate accumulation and reduced methane yield. Despite the importance of syntrophic butyrate oxidation in mitigating this effect, the microorganisms and interactions involved under high ...

Comparative Proteomics of Three Species of Ammonia-Oxidizing Bacteria. [PDF]
Front Microbiol, 2018 Ammonia-oxidizing bacteria (AOB) are important members of terrestrial, marine, and industrial microbial communities and play a fundamental role in the Nitrogen cycle within these systems. They are responsible for the first step of nitrification, ammonia oxidation to nitrite.

Shifts of ammonia-oxidation process along salinity gradient in an estuarine wetland
Ecological Indicators, 2022 Ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA) play an important role in nitrogen (N) cycling of the estuarine sediments. However, the shifts of potential ammonia oxidation rates (PARs) of AOA and AOB along different salinity ...
