Occurrence of Ammonia-Oxidizing Archaea in Wastewater Treatment Plant Bioreactors [PDF]
Applied and Environmental Microbiology, 2006 ABSTRACT We report molecular evidence that ammonia-oxidizing archaea (AOA) occur in activated sludge bioreactors used to remove ammonia from wastewater. Using PCR primers targeting archaeal ammonia monooxygenase subunit A ( amoA ) genes, we retrieved and compared 75 sequences from five wastewater treatment

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.Abstract Large‐scale application of methanol‐driven heterotrophic denitrification (MHD) biofilms to recirculating mariculture systems (RMSs) is constrained by the requirement of precise methanol dosage. The emergence of intelligent aquaculture offers an opportunity to address this challenge, necessitating a comprehensive understanding of the ...

Abundance and diversity of nitrogen-removing microorganisms in the UASB-anammox reactor.
PLoS ONE, 2019 Anaerobic ammonium oxidation is considered to be the most economical and low-energy biological nitrogen removal process. So far, anammox bacteria have not yet been purified from cultures.

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.Abstract Lake Salda (SW Turkey) is one of the most compelling terrestrial analogs for Jezero Crater on Mars due to its highly alkaline, Mg‐rich waters and hydromagnesite‐forming microbialites. This study integrates hydrochemical measurements, saturation‐index modeling, SEM–TEM imaging, and X‐ray diffraction (XRD) analysis to disentangle the biotic and ...

amoA Gene Abundances and Nitrification Potential Rates Suggest that Benthic Ammonia-Oxidizing Bacteria and Not Archaea Dominate N Cycling in the Colne Estuary, United Kingdom [PDF]
, 2015 Nitrification, mediated by ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA), is important in global nitrogen cycling. In estuaries where gradients of salinity and ammonia concentrations occur, there may be differential selections for ...

Nitrification and Nitrifying Bacteria in a Coastal Microbial Mat [PDF]
, 2015 The first step of nitrification, the oxidation of ammonia to nitrite, can be performed by ammonia-oxidizing archaea (AOA) or ammonium-oxidizing bacteria (AOB).

Advancement in Anaerobic Digestion for Scaling‐Up Biogas Production Through Food Waste Valorization
ChemBioEng Reviews, Volume 13, Issue 2, April 2026.The review article begins with an introduction that covers the overview, food waste (FW) classification, and the steps involved in producing biogas through anaerobic digestion (AD). Following that, it describes the process for producing biogas, including single‐, two‐, and multistage systems, mesophilic and thermophilic digestion, and wet and dry ...

Community Composition and Abundance of Bacterial, Archaeal and Nitrifying Populations in Savanna Soils on Contrasting Bedrock Material in Kruger National Park, South Africa [PDF]
, 2016 Savannas cover at least 13% of the global terrestrial surface and are often nutrient limited, especially by nitrogen. To gain a better understanding of their microbial diversity and the microbial nitrogen cycling in savanna soils, soil samples were ...
