Nitrogen transformation pathways, rates, and isotopic signatures in Lake Lugano [PDF]

, 2014
The consequences of detrimental alterations caused to the natural nitrogen (N) cycle are manifold. To tackle problems, such as eutrophication of coastal marine and lacustrine environments, or increasing emissions of greenhouse gas nitrous oxide (N2O ...

Denitrification in carbonate aquifers: a literature review

GEUS Bulletin
Denitrification is the most important process for nitrate removal in groundwater. Although carbonate aquifers are important for drinking water supply, the denitrification process in these systems is less understood than for unconsolidated sedimentary ...

Biochar‐based fertilizers improve nutrient use efficiency in sunflower grown on a subtropical tidal soil

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Improving fertilizer use efficiency is essential for reducing environmental pollution, sustaining agricultural production, and maximizing the economic profitability of crop production systems. This study tested the hypothesis that the formulation strategy of biochar‐based fertilizers, rather than nutrient addition alone, is associated with ...

Denitrification: from genes to ecosystems [PDF]

, 2010
Denitrification is a part of the global nitrogen cycle in which fixed nitrogen in the biosphere is returned to the atmosphere, which is mediated by diverse communities of microorganisms. This thesis seeks to gain a greater understanding of the ecology of

Research progress of autotrophic denitrification technology of sulfur, iron and sulfur-iron based electron donors

Gongye shui chuli
Autotrophic denitrification technology has the advantages of no additional carbon source, low sludge yield and low cost. It is one of the promising technologies for deep denitrification of low C/N wastewater under the dual-carbon background.

Rates and Pathways of N2 Production in a Persistently Anoxic Fjord: Saanich Inlet, British Columbia

Frontiers in Marine Science, 2019
Marine oxygen minimum zones (OMZs) support 30–50% of global fixed-nitrogen (N) loss but comprise only 7% of total ocean volume. This N-loss is driven by canonical denitrification and anaerobic ammonium oxidation (anammox), and the distribution and ...

Redefining the Nitrogen Cycle Through Electronic Configuration Driven Electrocatalysis for Low Carbon Energy

Carbon Energy, EarlyView.
This review reveals how electronic configuration engineering governs the entire electrocatalytic nitrogen cycle, providing structure‐informed insights into reaction selectivity, catalytic durability, and sustainable nitrogen utilization across energy and environmental systems. ABSTRACT The global nitrogen cycle is essential to food production, chemical

Activity and abundance of denitrifying bacteria in the subsurface biosphere of diffuse hydrothermal vents of the Juan de Fuca Ridge [PDF]

, 2012
Little is known about fixed nitrogen (N) transformation and elimination at diffuse hydrothermal vents where anoxic fluids are mixed with oxygenated crustal seawater prior to discharge.

Denitrification within the sediments and epiphyton of tropical macrophyte stands

, 2021
Excess nitrogen (N) is one of the most widespread and serious pollutants in the environment, but wetlands can reduce N loads, ameliorating its damaging effects downstream.

Contribution of Particulate and Mineral-Associated Organic Matter to Potential Denitrification of Agricultural Soils

Frontiers in Environmental Science, 2021
Water-extractable organic carbon (WEOC) is considered as the most important carbon (C) source for denitrifying organisms, but the contribution of individual organic matter (OM) fractions (i.e., particulate (POM) and mineral-associated (MOM)) to its ...
