Spatial Partitioning of Microbial Functional Potential Suggests Complex Nitrogen Cycling in a Subterranean Estuary [PDF]
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 ...

Denitrification Modularity and Its Environmental Controls in Transiently Versus Permanently Anoxic Marine Systems [PDF]
Environmental Microbiology, Volume 28, Issue 8, August 2026.Denitrification modularity is controlled by several environmental factors, especially concentrations of carbon and nitrogen substrates. In permanently anoxic environments, longer pathways are favored by high carbon/nitrate ratio, consistent with thermodynamic expectations and ecological models. In seasonal and transient anoxia, environmental complexity

The depth specific significiance, relative abundance and phylogeography of anaerobic ammonium oxidation (anammox) in marine and estuarine sediments [PDF]
, 2009 PhDThe availability of fixed forms of nitrogen is critical to the regulation of primary production. Until recently, denitrification (the sequential reduction of NO3 -, through NO2 - , to di-nitrogen gas) was recognised as the only significant pathway

Disturbance-based management of ecosystem services and disservices in partial nitritation-anammox biofilms [PDF]
, 2022 The resistance and resilience provided by functional redundancy, a common feature of microbial communities, is not always advantageous. An example is nitrite oxidation in partial nitritation-anammox (PNA) reactors designed for nitrogen removal in ...
