Lithology-driven soil properties control of N2O production by ammonia oxidizers in subtropical forest soils

open access: yesGeoderma
Lithology can strongly influence soil's physical and chemical properties, significantly affecting soil nitrogen (N) transformation rates. Ammonia-oxidizing archaea (AOA), ammonia-oxidizing bacteria (AOB) and complete ammonia oxidizers (comammox ...

Microbial Nitrogen Metabolism in Chloraminated Drinking Water Reservoirs

open access: yesmSphere, 2020
Ammonia availability due to chloramination can promote the growth of nitrifying organisms, which can deplete chloramine residuals and result in operational problems for drinking water utilities.

Biogeographic Patterns and Ecological Roles of Microorganisms in Sediments Along an Estuarine Salinity Gradient

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 4, August 2025.
From the river coastal to the adjacent sea waters, the diversity characteristics, community assembly processes, functional potential and community compositions of sedimentary microbial communities exhibit significant changes with increasing salinity levels.

DNA- and RNA-SIP Reveal Nitrospira spp. as Key Drivers of Nitrification in Groundwater-Fed Biofilters

open access: yesmBio, 2019
Nitrification, the oxidative process converting ammonia to nitrite and nitrate, is driven by microbes and plays a central role in the global nitrogen cycle.

Exploring Sulfate as an Alternative Electron Acceptor: A Potential Strategy to Mitigate N2O Emissions in Upland Arable Soils

open access: yesGlobal Change Biology, Volume 31, Issue 8, August 2025.
This study explored the use of sulfate‐based soil amendments as a new method to mitigate N2O—a powerful greenhouse gas—from agricultural soils. Laboratory and field experiments showed sulfate treatments significantly lowered N2O emissions without negatively affecting crop yields, mainly by altering soil microbial processes.

Sediments From a Seasonally Euxinic Coastal Ecosystem Show High Nitrogen Cycling Potential

open access: yesEnvironmental Microbiology, Volume 27, Issue 7, July 2025.
The nitrogen cycling potential of sediments from seasonally euxinic Lake Grevelingen was investigated through incubation experiments and 16S rRNA amplicon and shotgun metagenome sequencing. The sediments have a high potential for nitrification, denitrification, and DNRA, but not for anammox. ABSTRACT Coastal ecosystems are susceptible to eutrophication

Contrasting response of comammox Nitrospira, ammonia oxidising bacteria, and archaea to soil pH and nitrogen inputs

open access: yesScience of The Total Environment
This study aimed to investigate the effect of soil pH change, and nitrogen amendment on ammonia oxidiser abundance and comammox Nitrospira community composition. The experimental design used soil mesocosms placed in a temperature-controlled incubator for 90 days.

Vermicompost and Organic Manure Interactions: Effects on Heavy Metal Concentrations, Nitrification Activity, Comammox Nitrospira inopinata, and Archaea/Bacteria

open access: yes, 2023
Abstract Vermicompost is a substantial source of nutrients, promotes soil fertility, and maintains or increases soil organic matter levels. Potentially toxic elements (PTEs) in vermicompost impact on nitrification activity. However, it is yet unknown how vermicompost affects nitrifying bacteria and archaea, comammox Nitrospira inopinata ...

Exploring Suitable Nitrification Inhibitor in an Intensively Cultivated Greenhouse Soil and Its Effect on the Abundance and Community of Soil Ammonia Oxidizers

open access: yesAgronomy
The application of nitrification inhibitors (NIs) is an effective way to reduce soil nitrogen (N) losses and increase crop N uptake. Yet, the efficacy of NIs commonly varies with dosages, crop systems and soil environmental conditions.
