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.

Evaluation of Two Primer Sets for Amplification of Comammox Nitrospira amoA Genes in Wetland Soils

Frontiers in Microbiology, 2020
After the discovery of complete ammonia-oxidizing (comammox) Nitrospira, detection and assessments of the contribution of comammox Nitrospira communities to nitrogen cycling are in great demand.

Unveiling Global Diversity of Patescibacteriota and Functional Interactions with Host Microbes

Advanced Science, Volume 13, Issue 11, 23 February 2026.
Patescibacteriota represents a diverse group of ultra‐small epibiotic bacteria, which is largely overlooked. By integrating ribosomal protein S3‐based community profiling with MAG‐based metabolic potential analyses, this study provides new insights into their distribution, diversity, and potential interactions with other bacteria across diverse ...

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−)

Spatial and Temporal Variability of Microbial Nitrogen Cycling Genes in Arctic Streams

Global Biogeochemical Cycles, Volume 40, Issue 2, February 2026.
Abstract The Arctic is undergoing rapid climate change, with thawing permafrost and shifts in vegetation altering nitrogen (N) delivery into streams. These changes can significantly affect microbial biofilm diversity and functional roles, yet knowledge of streambed microbial biofilms remains scarce across the Arctic.

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.

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.

Unusual Plastoquinones in Non‐Phototrophic Nitrifying Bacteria

Environmental Microbiology Reports, Volume 17, Issue 4, August 2025.
Chemolithoautotrophic nitrifying bacteria of the genus Nitrospira exclusively possess unusual methyl‐plastoquinones with a standard redox potential below that of canonical plastoquinone and ubiquinone, suggesting functional roles in bidirectional electron transport.

Comparative genomics sheds light on niche differentiation and the evolutionary history of comammox Nitrospira [PDF]

The ISME Journal, 2017
Abstract The description of comammox Nitrospira spp., performing complete ammonia-to-nitrate oxidation, and their co-occurrence with canonical β-proteobacterial ammonia oxidizing bacteria (β-AOB) in the environment, calls into question the metabolic potential of comammox Nitrospira and the evolutionary history of their ammonia ...

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.
