Phanerozoic radiation of ammonia oxidizing bacteria [PDF]

open access: yesScientific Reports, 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 ...

Characterization of a long overlooked copper protein from methane- and ammonia-oxidizing bacteria [PDF]

open access: yesNature Communications, 2018
Methane- and ammonia-oxidizing bacteria use the integral membrane, copper-dependent enzymes particulate methane monooxygenase (pMMO) and ammonia monooxygenase (AMO) to oxidize methane and ammonia.

Selective Enrichment of Nitrososphaera viennensis-Like Ammonia-Oxidizing Archaea over Ammonia-Oxidizing Bacteria from Drinking Water Biofilms [PDF]

open access: yesMicrobiology Spectrum, 2022
Ammonia-oxidizing archaea (AOA) can oxidize ammonia to nitrite for energy gain. They have been detected in chloraminated drinking water distribution systems (DWDS) along with the more common ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria

Ammonia-Oxidizing Archaea (AOA) Play with Ammonia-Oxidizing Bacteria (AOB) in Nitrogen Removal from Wastewater. [PDF]

open access: yesArchaea, 2018
An increase in the number of publications in recent years indicates that besides ammonia-oxidizing bacteria (AOB), ammonia-oxidizing archaea (AOA) may play an important role in nitrogen removal from wastewater, gaining wide attention in the wastewater ...

Ammonia oxidizers offset acidification stress via adaptive substrate affinity in aquatic ecosystems [PDF]

open access: yesNature Communications
Ammonia oxidation, a critical nitrogen cycle process, exhibits contradictory responses to aquatic acidification, and the underlying mechanism remains unresolved. Here, through pH manipulation experiments across diverse ecosystems and with a model ammonia-

Comparative Proteomics of Three Species of Ammonia-Oxidizing Bacteria. [PDF]

open access: yesFront 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.

Immobilization of ammonia-oxidizing bacteria by polyvinyl alcohol and sodium alginate. [PDF]

open access: yesBraz J Microbiol, 2017
Ammonia-oxidizing bacteria were immobilized by polyvinyl alcohol (PVA) and sodium alginate. The immobilization conditions and ammonia oxidation ability of the immobilized bacteria were investigated.

A review of ammonia-oxidizing bacteria and archaea in Chinese soils [PDF]

open access: yesFrontiers 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 ...

Growth of Nitrosococcus-Related Ammonia Oxidizing Bacteria Coincides with Extremely Low pH Values in Wastewater with High Ammonia Content. [PDF]

open access: yesEnviron Sci Technol, 2017
Ammonia oxidation decreases the pH in wastewaters where alkalinity is limited relative to total ammonia. The activity of ammonia oxidizing bacteria (AOB), however, typically decreases with pH and often ceases completely in slightly acidic wastewaters ...
