The Use of Hydrogel Beads to Immobilise Active Ammonia-Oxidizing Archaea

Ruby John

One of the most common clades of mesophilic and thermophilic Thaumarchaeota are ammonium-oxidizing archaea. They play an important part in the global nitrogen cycle and can be found in terrestrial, marine, and geothermal habitats. Their existence in activated sludge reactors and wastewater treatment plants suggests that they, like their bacterial counterparts, play a role in ammonium removal. Ammonia-Oxidizing Archaea (AOA) combines with anaerobic ammonium oxidising bacteria in the Oxygen Minimum Zones (OMZ), causing up to 50% of the ocean's nitrogen loss
