Abundance and diversity of nitrogen-removing microorganisms in the UASB-anammox reactor.
PLoS ONE, 2019 Anaerobic ammonium oxidation is considered to be the most economical and low-energy biological nitrogen removal process. So far, anammox bacteria have not yet been purified from cultures.

Indigenous Ammonia-Oxidizing Archaea in Oxic Subseafloor Oceanic Crust
mSystems, 2020 Oceanic ridge flank systems represent one of the largest and least-explored microbial habitats on Earth. Fundamental ecological questions regarding community activity, recruitment, and succession in this environment remain unanswered.

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 3, September 2026.ABSTRACT The development of biofertilization strategies based on arbuscular mycorrhizal fungi (AMF) represents a promising approach to enhance crop productivity and soil health while reducing the environmental footprint of conventional fertilization. This study evaluated the effects of Glomus iranicum var.

Serpentine Biocrust Microbes Maintain Nitrogen Cycling Under Drought and Heavy Metal Stress
Ecological Research, Volume 41, Issue 5, September 2026.This study highlights the complex interplay between soil geochemistry and moisture availability in shaping microbial communities within wetter and drier serpentine and non‐serpentine biological soil crusts. It demonstrates that both factors influence the structure of nitrogen‐cycling microbial communities and the processes they mediate.

Relative contributions of archaea and bacteria to aerobic ammonia oxidation in the environment [PDF]
Environmental Microbiology, 2008 Summary Traditionally, organisms responsible for major biogeochemical cycling processes have been determined by physiological characterization of environmental isolates in laboratory culture. Molecular techniques have, however, confirmed the widespread occurrence of abundant bacterial and archaeal groups with no cultivated ...

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.ABSTRACT Abalone are economically, ecologically and culturally significant marine molluscs, with both wild and farmed populations under pressure due to intrinsic and extrinsic stressors. Abalone performance and health are centred on a highly specialized digestive system supported by a diverse gut microbiome, which enables nutrient assimilation ...

mSphere, 2016 We report metagenomic evidence for the presence of a Nitrospira-like organism with the metabolic potential to perform the complete oxidation of ammonia to nitrate (i.e., it is a complete ammonia oxidizer [comammox]) in a drinking water system.

Opportunities and Challenges of the Electrosynthesis of Nitrites and Nitrates From Ammonia
ChemCatChem, Volume 18, Issue 16, 27 August 2026.Future progress on the electrosynthesis of nitrates and nitrites requires an integrated approach to enable consolidation of the mechanistic understanding in the short‐term, robust operation of all components at the electrolyser prototype level in the medium‐term, and integration into renewable power networks for sustainable fertilizer production in the

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 8, Page 1632-1642, August 2026.Abstract BACKGROUND Landfill gas (LFG) and leachate are commonly treated separately through energy‐intensive processes. This study evaluated the integration of both streams in an anaerobic biotrickling filter (BTF) to achieve simultaneous methane (CH4) and carbon dioxide (CO2) removal coupled with ammonium (NH4+) transformation, and how the microbial ...

Environmental Microbiology, Volume 28, Issue 8, August 2026.Microbial communities in a Mediterranean subterranean estuary show spatially structured nitrogen‐cycling potential across hydrochemical zones. Microbial properties, more than environmental variables, predict NO2− and NH4+ concentrations, highlighting their key role in controlling nitrogen transformations prior to submarine groundwater discharge ...
