Understanding the factors (salinity, nitrate, and carbon availability) and mechanisms that control N2O products and nitrate removal patterns in inland saline farmland ditches

Vadose Zone Journal, Volume 25, Issue 3, May/June 2026.
Abstract Denitrification, the microbial process by which nitrate (NO3−) in aquatic systems is converted to N2 and N2O, is widely recognized as an effective and environmentally friendly method for mitigating NO3− pollution in water bodies. However, the complex role of salinity, which could significantly influence the denitrification process, in salt ...

The ability of sulfate-reducing bacteria Desulfovibrio desulfuricans Ya-11 i Desulfobacter sp. to use nitrate as electron acceptor

Біологічні студії, 2011
The ability of Desulfovibrio desulfuricans Ya-11 bacteria to use nitrate as terminal electron acceptor was studied. The level of biomass accumulation in the medium with nitrate changed depending on the initial NO3– concentration. At nitrate concentration

Microbiologically influenced corrosion of steel in coastal surface seawater contaminated by crude oil

npj Materials Degradation, 2022
Petroleum-hydrocarbons spilt in surface seawater may pose potential threats to the corrosion of steel infrastructures. We show that crude oil accelerated steel corrosion mainly by accelerating microbiologically influenced corrosion (MIC).

Biomass-supported catalysts on Desulfovibrio desulfuricans and Rhodobacter sphaeroides [PDF]

, 2008
A Rhodobacter sphaeroides-supported dried, ground palladium catalyst (‘‘Rs-Pd(0)’’) was compared with a Desulfovibrio desulfuricans-supported catalyst (‘‘Dd-Pd(0)’’)and with unsupported palladium metal particles made by reduction under H2 (‘‘Chem-Pd(0)’’)

Nitrogen cycling in Sabine Lake [PDF]

, 2001
As a part of continuing efforts to investigate nitrogen cycling in Texas estuaries, denitrification, nitrogen fixation, dissimilatory nitrate reduction to ammonium (DNRA), and sediment oxygen demand were measured in Sabine Lake, Texas.

Blue Nitrogen: Global Rates and Economic Importance

Earth's Future, Volume 14, Issue 5, May 2026.
Abstract Nitrogen (N) pollution drives widespread coastal ecosystem collapse. In this paper, we argue that mangrove forests represent an undervalued natural mitigation solution for N pollution. By performing a comprehensive global meta‐analysis, we reveal that mangroves remove 870 Gg N annually, which represents an economic value reaching $8.7 billion ...

Adenosine-5′-Phosphosulfate- and Sulfite Reductases Activities of Sulfate-Reducing Bacteria from Various Environments

Biomolecules, 2020
A comparative study of the kinetic characteristics (specific activity, initial and maximum rate, and affinity for substrates) of key enzymes of assimilatory sulfate reduction (APS reductase and dissimilatory sulfite reductase) in cell-free extracts of ...

Genomic insight of sulfate reducing bacterial genus Desulfofaba reveals their metabolic versatility in biogeochemical cycling

BMC Genomics, 2023
Background Sulfate-reducing bacteria (SRB) drive the ocean sulfur and carbon cycling. They constitute a diverse phylogenetic and physiological group and are widely distributed in anoxic marine environments.

Putative Analogs of Pyrite Suns Forming in Proglacial Alaska Mudflats

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Disc‐shaped pyrite suns of the Pennsylvanian age Anna Shale are thought to have formed where pressure restricted pyrite crystal growth to a flattened disc shape during diagenesis at the Anna Shale and the underlying Herrin coal boundary.

Spatial Variability in Trace Organic Compound Reactivity During Urban River Infiltration Into an Alluvial Aquifer

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Trace organic compounds (TrOCs) in lotic systems pose risks for ecosystem and human health. TrOCs can enter groundwater along losing river sections, yet little is known about the spatial extent of infiltration zones and the biogeochemical factors controlling the spatial variability of TrOC reactivity and removal, particularly along river‐to ...
