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.

Image_1_Differential responses of canonical nitrifiers and comammox Nitrospira to long-term fertilization in an Alfisol of Northeast China.PDF

, 2023
The newly identified complete ammonia oxidizer (comammox) that converts ammonia directly into nitrate has redefined the long-held paradigm of two-step nitrification mediated by two distinct groups of nitrifiers.

Nitrogen Kinetic Isotope Effects of Nitrification by the Complete Ammonia Oxidizer Nitrospira inopinata

mSphere, 2021
Analysis of nitrogen isotope fractionation effects is useful for tracing biogeochemical nitrogen cycle processes. Nitrification can cause large nitrogen isotope effects through the enzymatic oxidation of ammonia (NH3) via nitrite (NO2−) to nitrate (NO3−)

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.

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

Comammox Nitrospira play an active role in nitrification of agricultural soils amended with nitrogen fertilizers

, 2019
The recent discovery of complete ammonia oxidizers (comammox Nitrospira) challenged the paradigm of the two-step nitrification mediated by two distinct groups of nitrifiers, and raised fundamental questions regarding their niche specialization and ...

Nitrogen source influences the interactions of comammox bacteria with aerobic nitrifiers

Microbiology Spectrum
While the co-existence of comammox Nitrospira with canonical nitrifiers is well documented in diverse ecosystems, there is still a dearth of knowledge about the mechanisms underpinning their interactions.
