Nitrogen removal and ammonia-oxidising bacteria in a vertical flow constructed wetland treating inorganic wastewater [PDF]
Nitrogen removal performance and the ammonia-oxidising bacterial (AOB) community were assessed in the batch loaded 1.3ha saturated surface vertical flow wetland at CSBP Ltd, a fertiliser and chemical manufacturer located in Kwinana, Western Australia ...

Unifying the global phylogeny and environmental distribution of ammonia-oxidising archaea based on amoA genes [PDF]
AbstractAmmonia-oxidising archaea (AOA) are ubiquitous and abundant in nature and play a major role in nitrogen cycling. AOA have been studied intensively based on the amoA gene (encoding ammonia monooxygenase subunit A), making it the most sequenced functional marker gene.

Long‐Term Low‐DO Operation Changes the Ammonia Oxidizer Community and Oxygen Kinetics
Lower dissolved oxygen reduces energy demand for wastewater treatment but slows ammonia removal. This study investigates a pilot process maintaining complete nitrification, documenting ammonia oxidizer adaptation to low dissolved oxygen. ABSTRACT Low–dissolved oxygen (DO) biological nutrient removal is an attractive option for energy and cost reduction,

Abstract Dredged sediments are rich in organic matter and nutrients, but their agricultural reuse is limited by high salinity. Electrokinetic remediation (EKR) can remove salts, yet its effect on overall soil health, including microbial function and plant nutrient dynamics, remains poorly understood.

Correlation between nitrate production rates and amoA abundance.
Coefficients of determination (r2) for the correlation between the nitrate production rates and the number of amoA transcripts and genes. The coefficients were determined for the bacterial, archaeal or total summed amoA for either N-amended or non ...

This study investigated the influence of salinity and ammonium levels on ammonia-oxidizing bacteria (AOB) and archaea (AOA) by monitoring their amo subunit A (amoA) messenger RNA (mRNA) expression. The aerobic mini-continuous stirred-tank reactors (mini-CSTRs) were operated for 48 h under different salinity or ammonium levels.

Among South Asian women, those with larger organ mass and energy expenditure, indicating greater capacity to promote fetal growth, had larger pelvic dimensions, partly explained by linear growth patterns. However, body fat correlated with energy expenditure but not pelvic dimensions, helping explain why high adiposity increases risk of obstructed ...

Abundance and diversity of ammonia-oxidizing archaea and bacteria in sediments of trophic end members of the Laurentian Great Lakes, Erie and Superior. [PDF]
Ammonia oxidation is the first step of nitrification carried out by ammonia-oxidizing Archaea (AOA) and Bacteria (AOB). Lake Superior and Erie are part of the Great Lakes system differing in trophic status with Lake Superior being oligotrophic and Lake ...

Biochar has been widely recognized as an effective and eco-friendly ameliorant for saline soils, but information about the mechanism of how biochar influences nitrification in salt-affected agroecosystem remains fragmented.
