Limnology and Oceanography, Volume 71, Issue 1, January 2026.Abstract Organotrophic denitrification is an important nitrogen (N) removal process in lakes, but alternative N reduction processes such as lithotrophic sulfur (S)‐oxidizing denitrification may be greatly underappreciated. We studied the redox transition zone (RTZ) in the meromictic water column of the North Basin of Lake Lugano (Switzerland) to ...

Water Research XBacterial cooperation is very important for anammox bacteria which perform low-carbon and energy-efficient nitrogen removal, yet its variation to adapt to high NH4+-N concentration in actual wastewater treatment plants (WWTPs) remains unclear.

Another way to divide: the case of anammox bacteria [PDF]
Molecular Microbiology, 2009 SummaryAnammox bacteria exhibit remarkable and characteristic metabolic features that enable them to oxidize ammonium under anoxic conditions. Their ultrastructure is complex, with three compartments, comprising paryphoplasm, the riboplasm and the anammoxosome.

Eutrophication Reshapes Microbial Communities and Life‐History Strategies in the Riverine Ecosystems
Environmental Microbiology Reports, Volume 17, Issue 6, December 2025.We use 16S rRNA amplicon and shotgun metagenomic sequencing to assess the microbiome in urban and natural riverine ecosystems. This study reveals that eutrophication reshapes microbial communities and demonstrates a tendency toward r‐strategy traits in urban river ecosystems.

Nutrient removal from UASB effluent in agro-industries [PDF]
, 2011 Phosphorus and nitrogen are important elements, making a major contribution to agricultural and industrial development, but their release to natural water bodies are the main causes of eutrophication. Anaerobic digestion yields effluents rich in ammonium

Nitrification-denitrification in WSP: a mechanism for permanent nitrogen removal in maturation ponds [PDF]
, 2009 A pilot-scale primary maturation pond was spiked with 15N-labelled ammonia (15NH4Cl) and 15N labelled nitrite (Na15NO2), in order to improve current understanding of the dynamics of inorganic nitrogen transformations and removal in WSP systems.

Microbial community shifts on an anammox reactor after a temperature shock using 454-pyrosequencing analysis [PDF]
, 2015 To explore the changes in the microbial community structure during the recovery process of an anammox reactor after a temperature shock, the 454-pyrosequencing technique was used. The temperature shock reduced the nitrogen removal rate up to 92% compared
