Nitrogen removal in a two-chambered microbial fuel cell: Establishment of a nitrifying-denitrifying microbial community on an intermittent aerated cathode [PDF]
, 2016 A microbial fuel cell (MFC) was used to study nitrogen dynamics and its feasibility for high strength wastewater treatment. Intermittent aeration was applied on the cathode chamber accomplishing the establishment of a simultaneous nitrifying-denitrifying

Nitrifier Gene Abundance and Diversity in Sediments Impacted by Acid Mine Drainage
Frontiers in Microbiology, 2017 Extremely acidic and metal-rich acid mine drainage (AMD) waters can have severe toxicological effects on aquatic ecosystems. AMD has been shown to completely halt nitrification, which plays an important role in transferring nitrogen to higher organisms ...

Comammox Nitrospira abundance and contribution to nitrification in a forested landscape
EcosphereNitrification in terrestrial ecosystems is mediated by NH4+‐oxidizing bacteria (AOB) and archaea (AOA). Presently, we understand relatively little about how physiological capacities and environmental tolerances influence their community composition, and ...

The hidden potential of archaea in carbon and nitrogen cycling in agricultural soils: a review
Frontiers in MicrobiologyThe soil microbiome drives soil nutrient cycling and is intrinsically linked to plant productivity in agriculture. Archaea are members of many soil microbiomes and play important roles in nutrient cycling, particularly in the carbon and nitrogen cycle ...
