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

Environmental 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.

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

Global 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.

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

mBio, 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.

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

Environmental 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

Compound drought-heat legacies promote the contribution of comammox Nitrospira to N2O emissions: as evidenced from both acidic and alkaline soils

Geoderma
The responses of complete ammonia oxidization (comammox) to compound drought and heat and their contributions to post-drought nitrous oxide (N2O) emissions remain unclear.

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

Geoderma
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 ...

Establishment and calibration of consensus process model for nitrous oxide dynamics in water quality engineering [PDF]

, 2017
Forskning i biologisk kvælstoffjernelse på spildevandsrensningsanlæg har historisk fokuseret på at opnå en god udledningskvalitet, mens opmærksom-heden de seneste år er blevet rettet mod energibesparelser og CO2-udslip.

Evaluation of the process performance of comammox-like nitrospira dominant down-flow hanging sponge reactor with reduced nitrous oxide emissions

Water Research X
Nitrification/denitrification mitigates excess nitrogen in wastewater and reduces nutrient pollution in recipient surface waters but emits substantial amounts of nitrous oxide (N₂O).

Investigating microbial and environmental drivers of nitrification in alkaline forest soil. [PDF]

ISME Commun
Ammonia oxidation is a key step in the biogeochemical cycling of nitrogen, and soils are important ecosystems for nitrogen flux globally. Approximately 25% of the world’s soils are alkaline.
