The anammoxosome: an intracytoplasmic compartment in anammox bacteria [PDF]

FEMS Microbiology Letters, 2004
Anammox bacteria belong to the phylum Planctomycetes and perform anaerobic ammonium oxidation (anammox); they oxidize ammonium with nitrite as the electron acceptor to yield dinitrogen gas. The anammox reaction takes place inside the anammoxosome: an intracytoplasmic compartment bounded by a single ladderane lipid-containing membrane.

Aquifer Microbial Communities Differentially Display Metabolisms Capable of Secondary Effects on Uranium Speciation Across a Former Metal Processing Site

Environmental Microbiology, Volume 28, Issue 9, September 2026.
We performed microbial membership and metabolism measurements across a uranium‐contaminated site's surface and ground waters, then performed analyses relating these metrics to geochemistry at the site. Findings showed variations in the membership, yet mainly similar functional capabilities.

Prokaryotic Novelty and Metabolic Diversity in the Tagoro Shallow Hydrothermal System (Canary Islands, Spain)

Environmental Microbiology, Volume 28, Issue 9, September 2026.
Hydrothermal activity at the Tagoro submarine volcano shapes distinct epipelagic and benthic prokaryotic communities. Microbial diversity decreases towards vent sources, yet novel taxa dominate and potentially contribute to iron, nitrogen, sulphur and methane cycling in this shallow hydrothermal system with high unexplored microbial diversity ...

ANAMMOX IN A TEMPERATE ESTUARY [PDF]

, 2014
PhDThe seasonal variation of anammox is yet to be comprehensively studied, unlike denitrification, the more traditional sink for fixed nitrogen. A seasonal study of anammox, denitrification and benthic oxygen consumption using the revised isotope pairing

Characterization of Anammox Bacteria from Marine Water and Sediment Samples

Jurnal Presipitasi, 2023
Anammox activity of water and sediment taken from marine ecosistem around Semarang were investigated in anammox media agar and batch reactor. Effect of increasing salinities (3% to 5%, 7% and 9%) and decreasing salinities (3% to 2%, 1% and 0%) were ...

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

Effect of ammonium concentration on methane oxidation and CO2 removal in an anaerobic biotrickling filter treating synthetic landfill gas and leachate

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 ...

Partial denitrification providing nitrite: Opportunities of extending application for anammox

Environment International, 2019
Anaerobic ammonium oxidation (anammox) has been extensively investigated for cost-efficient nitrogen removal from wastewater. However, the major issues of nitrate (NO3−-N) residue and instability in the current combination of nitritation and anammox ...
