Small-scale variation of ammonia oxidisers within intertidal sediments dominated by ammonia-oxidising bacteria Nitrosomonas sp. amoA genes and transcripts

Scientific Reports, 2017
While numerous studies have investigated the abundance of ammonia oxidising bacteria and archaea (AOB/AOA) via the ammonia monooxygenase gene amoA, less is known about their small-scale variation and if amoA gene abundance equates to activity.

Hydrazine Synthase From Anammox Is Inhibited by Linear and Aromatic Alkynes

Environmental Microbiology, Volume 28, Issue 3, March 2026.
Linear and aromatic alkynes inhibit anammox in culture and in wetlands. The inhibition by alkynes is specific to the hydrazine synthase, a key enzyme in the anammox pathway. ABSTRACT N2O emissions by nitrifiers are often estimated using selective inhibitors, such as 1‐alkynes.

Enhanced Phosphorus Removal From Municipal Wastewater via Cotreatment of Mine Drainage During Primary Clarification

Water Environment Research, Volume 98, Issue 2, February 2026.
Cotreating acid mine drainage with municipal wastewater in existing WWTPs can enhance phosphorus and BOD removal without compromising treatment performance. The approach offers a cost‐effective, infrastructure‐efficient solution that leverages existing plant capacity while decreasing nutrient loads and supporting environmental goals in mining regions ...

Chemolithoorganotrophic Growth of Nitrosomonas europaea on Fructose [PDF]

Journal of Bacteriology, 2003
ABSTRACT The nitrifying bacterium Nitrosomonas europaea can obtain all its carbon for growth from CO 2 and all its energy and reductant for growth from the oxidation of NH 3 and is considered an obligate chemolithoautotroph. Previous studies have shown that

A Potentiometric Flow Biosensor Based on Ammonia-Oxidizing Bacteria for the Detection of Toxicity in Water [PDF]

, 2013
A flow biosensor for the detection of toxicity in water using the ammonia-oxidizing bacterium (AOB) Nitrosomonas europaea as a bioreceptor and a polymeric membrane ammonium-selective electrode as a transducer is described.

Model Investigation of Nitrification Inhibitor Effects on Nitrous Oxide Emissions From Manure Hotspots

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 2, February 2026.
Abstract Manure application to cropland stimulates soil nitrogen transformations, and the uneven distribution of manure in the soil creates organic hotspots, which may cause extended pulses of nitrous oxide (N2O) and di‐nitrogen (N2) emissions. Amending liquid manure (slurry) with a nitrification inhibitor (NI) can reduce N2O emissions, but the ...

Changes in community composition of ammonia-oxidizing betaproteobacteria from stands of Black mangrove (Avicennia germinans) in response to ammonia enrichment and more oxic conditions

Frontiers in Microbiology, 2013
In flooded and non-flooded impounded forests of Black mangrove (Avicennia germinans), the community structure of the ammonia-oxidizing betaproteobacteria (β-AOB) differed among distinct mangrove vegetation cover types and hydrological regimes.

Community Dynamics and Antibiotic Resistance Gene Profile of Gut Microbiota in Labeo rohita Sourced From Various Catches in Retail Fish Markets in Kolkata, India

Journal of Food Safety, Volume 46, Issue 1, February 2026.
The study compared gut microbiota and antibiotic resistance genes (ARGs) in retail Labeo rohita from local and out‐of‐state sources using molecular and NGS methods. Proteobacteria dominated both groups, with Aeromonas prevalent. Region‐specific ARGs indicate environmental influences.
