Ammonia-oxidizing archaea and complete ammonia-oxidizing Nitrospira in water treatment systems
Water Research X, 2022 Nitrification, the oxidation of ammonia to nitrate via nitrite, is important for many engineered water treatment systems. The sequential steps of this respiratory process are carried out by distinct microbial guilds, including ammonia-oxidizing bacteria (

Ammonia oxidation at pH 2.5 by a new gammaproteobacterial ammonia-oxidizing bacterium. [PDF]
ISME J, 2021 Abstract Ammonia oxidation was considered impossible under highly acidic conditions, as the protonation of ammonia leads to decreased substrate availability and formation of toxic nitrogenous compounds. Recently, some studies described archaeal and bacterial ammonia oxidizers growing at pH as low as 4, while environmental studies ...

Activity-based labelling of ammonia- and alkane-oxidizing microorganisms including ammonia-oxidizing archaea [PDF]
ISME Communications, 2023 Abstract Recently, an activity-based labelling protocol for the in situ detection of ammonia- and alkane-oxidizing bacteria became available. This functional tagging technique enabled targeted studies of these environmentally widespread functional groups, but it failed to capture ammonia-oxidizing archaea (AOA). Since their first discovery, AOA

Nitric oxide scavengers differentially inhibit ammonia oxidation in ammonia-oxidizing archaea and bacteria [PDF]
FEMS Microbiology Letters, 2016 Differential inhibitors are important for measuring the relative contributions of microbial groups, such as ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA), to biogeochemical processes in environmental samples. In particular, 2-phenyl-4,4,5,5-tetramethylimidazoline-1-oxyl 3-oxide (PTIO) represents a nitric oxide scavenger used for ...

Ammonia-oxidizing archaea have more important role than ammonia-oxidizing bacteria in ammonia oxidation of strongly acidic soils [PDF]
The ISME Journal, 2011 Abstract Increasing evidence demonstrated the involvement of ammonia-oxidizing archaea (AOA) in the global nitrogen cycle, but the relative contributions of AOA and ammonia-oxidizing bacteria (AOB) to ammonia oxidation are still in debate. Previous studies suggest that AOA would be more adapted to ammonia-limited oligotrophic conditions,

Catalytic ammonia oxidation to nitrogen (I) oxide [PDF]
Austrian Journal of Technical and Natural Sciences, 2015 The process of synthesis of nitrous oxide by low-temperature catalytical oxidation of NH has been investigated for organic synthesis. The investigation has been carried out by the stage separation approach with NH oxidation occurring in several reaction zones, which characterized by different catalytic conditions.

Aerobic metabolism of mixed culture of ammonia oxidation
浙江大学学报. 农业与生命科学版, 2000 Denitrification with ammonia as electron donor is a new microbial reaction, named anaerobic ammonia oxidation. The characteristics of mixed culture from an anaerobic ammonia oxidation reactor are compared with those of Nitrosomonas europaea and those of ...
