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 ...

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.

Insights into the Variations of Hao-Dependent Nitrifying and Nir-Dependent Denitrifying Microbial Communities in Ammonium-Graduated Lake Environments

Applied Sciences, 2019
Biological nitrification and denitrification play significant roles in nitrogen-associated biogeochemical cycles. However, our understanding of the spatial scales at which microbial communities act and vary is limited.

Influence of trace erythromycin and eryhthromycin-H2O on carbon and nutrients removal and on resistance selection in sequencing batch reactors (SBRs). [PDF]

, 2009
Three sequencing batch reactors (SBRs) were operated in parallel to study the effects of trace erythromycin (ERY) and ERY-H2O on the treatment of a synthetic wastewater.

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 ...

Influence of tetracycline on the microbial community composition and activity of nitrifying biofilms [PDF]

, 2014
The present work aims to evaluate the bacterial composition and activity (carbon and nitrogen removal) of nitrifying biofilms exposed to 50 μg L−1 of tetracycline.

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.

Genes and pathways for CO2 fixation in the obligate, chemolithoautotrophic acidophile, Acidithiobacillus ferrooxidans, Carbon fixation in A. ferrooxidans [PDF]

, 2010
Background: Acidithiobacillus ferrooxidans is chemolithoautotrophic gamma-proteobacterium that thrives at extremely low pH (pH 1-2). Although a substantial amount of information is available regarding CO2 uptake and fixation in a variety of facultative ...

Microbial nitrogen removal and recycling in the redox transition zone of a meromictic lake and its coupling to sulfur cycling

Limnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract Organotrophic denitrification is an important nitrogen (N) removal process in lakes, but alternative N reduction processes such as lithotrophic sulfur (S)‐oxidizing denitrification may be greatly underappreciated. We studied the redox transition zone (RTZ) in the meromictic water column of the North Basin of Lake Lugano (Switzerland) to ...

The impact of molecular biology on assessment of water quality: advantages and limitations of current techniques [PDF]

, 1997
The advent of molecular biology has had a dramatic impact on all aspects of biology, not least applied microbial ecology. Microbiological testing of water has traditionally depended largely on culture techniques.
