Genome-centered metagenomics illuminates adaptations of core members to a partial Nitritation–Anammox bioreactor under periodic microaeration

Frontiers in Microbiology, 2023
The partial nitritation-anaerobic ammonium oxidation (anammox; PN-A) process has been considered a sustainable method for wastewater ammonium removal, with recent attempts to treat low-strength wastewater.

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 ...

Design and Assessment of Species-Level qPCR Primers Targeting Comammox

Frontiers in Microbiology, 2019
Published PCR primers targeting the ammonia monooxygenase gene (amoA) were applied to samples from activated sludge systems operated with low dissolved oxygen (DO) to quantify total and clade-level Nitrospira that perform complete ammonium oxidation ...

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.

Rapid nitrification involving comammox and canonical Nitrospira at extreme pH in saline‐alkaline lakes

Environmental Microbiology, 2023
Abstract Nitrite‐oxidizing bacteria (NOB) catalyse the second nitrification step and are the main biological source of nitrate. The most diverse and widespread NOB genus is Nitrospira , which also contains complete ammonia oxidizers (comammox) that oxidize ammonia to nitrate.

Genomic and Physiological Characteristics of a Novel Nitrite-Oxidizing Nitrospira Strain Isolated From a Drinking Water Treatment Plant

Frontiers in Microbiology, 2020
Nitrite-oxidizing bacteria (NOB) catalyze the second step of nitrification, which is an important process of the biogeochemical nitrogen cycle and is exploited extensively as a biological nitrogen removal process.

Primer evaluation and development of a droplet digital PCR protocol targeting amoA genes for the quantification of Comammox in lakes

Scientific Reports, 2021
To date, little is known about the ecological significance of Comammox (COMplete AMMonia OXidizers) Nitrospira in the water column of freshwater lakes. Water samples collected along depth profiles were used to investigate the distribution of Comammox in ...

Composition and activity of nitrifier communities in soil are unresponsive to elevated temperature and CO2, but strongly affected by drought [PDF]

, 2020
Nitrification is a fundamental process in terrestrial nitrogen cycling. However, detailed information on how climate change affects the structure of nitrifier communities is lacking, specifically from experiments in which multiple climate change factors ...

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.
