Submerged plants alleviated the impacts of increased ammonium pollution on anammox bacteria and nirS denitrifiers in the rhizosphere

, 2021
Excess nitrogen input into water bodies can cause eutrophication and affect the community structure and abundance of the nitrogen-transforming microorganisms; thus, it is essential to remove nitrogen from eutrophic water bodies.

Microbially driven organic carbon cycling at the land−sea interface: Advances and an integrated study framework

mLife, Volume 5, Issue 3, Page 282-295, June 2026.
Abstract The land−sea interface is a vital component of global biogeochemical cycles, where microorganisms drive the cycling of carbon, nitrogen, and sulfur. This review synthesizes the research progress from representative land−sea interfaces to elucidate how the microbial community structure and metabolic function influence the mobilization ...

Decoupling Dissolution and Biological Kinetics in Polycaprolactone‐Based Denitrification: Direct Determination of Yield and Maximum Specific Growth Rate

Water Environment Research, Volume 98, Issue 6, June 2026.
The graphical abstract compares methanol and presolubilized PCL as external carbon sources in anoxic batch denitrification tests. Although both substrates showed comparable biomass yields, presolubilized PCL supported a higher maximum growth rate than methanol.

Microbial ecology of anammox bacteria in estuarine and oxygen minimum zone environments [PDF]

Anammox (anaerobic ammonium oxidation) is an environmentally significant process with great importance for global biogeochemical cycles. This process is mediated by a unique suite of phylogenetically distinct chemolithoautotrophic bacteria which ...

Anaerobic ammonium oxidation (anammox) bacterial diversity, abundance, and activity in marsh sediments of the Yangtze Estuary [PDF]

, 2013
Anaerobic ammonium oxidation (anammox) as an important process of nitrogen cycle has been studied in estuarine environments. However, knowledge about the dynamics of anammox bacteria and their interactions with associated activity remains scarce in these

Blue Nitrogen Follows the Fate of Tidal Wetlands

Earth's Future, Volume 14, Issue 6, June 2026.
Abstract Tidal wetlands sequester carbon (C) at much higher rates per area than other ecosystems, helping to offset C emissions. The burial of organic C in tidal wetland soils, “blue C”, is tightly linked to the cycling of nitrogen (N), which is a key pollutant and limiting nutrient for many ecosystems.

Fate of dissolved organic nitrogen during the Anammox process using ultra-high resolution mass spectrometry

Environment International, 2019
Anaerobic ammonium oxidation (Anammox) is a cost-effective process for treating highly nitrogenous wastewater. However, the fate of organic nitrogen during Anammox treatment is still unclear, which limits its practical application.

Impacts of Climate Change on Groundwater Quality in the Northern Atlantic Coastal Plain: A Review

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 3, June 2026.
ABSTRACT This review integrates hydrogeological and geochemical processes to assess the impacts of climate change on groundwater quality in the Northern Atlantic Coastal Plain (NACP). Projected changes in air temperature, precipitation, and sea‐level rise are expected to influence groundwater recharge, discharge, storage, and seawater intrusion in ...

Microplastic addition has no detectable effect on ecosystem metabolism or diel dinitrogen flux in a large in‐lake mesocosm experiment under oligotrophic conditions

Limnology and Oceanography, Volume 71, Issue 5, May 2026.
Abstract Ecosystem metabolism (e.g., gross primary production [GPP], respiration [R], and net ecosystem production) integrates the activity of aerobic organisms and is an indicator of environmental change. Microplastics (i.e., particles 1–5 mm) are widespread in freshwater ecosystems and are colonized by biofilms and other organisms.
