Implementing potential climate‐smart practices through diverse partnerships

PLANTS, PEOPLE, PLANET, EarlyView.
Climate change is one of the greatest threats to society, negatively impacting agriculture and crop yields. Globally, agriculture is also one of the largest greenhouse gas (GHG) emitting sectors. Climate‐smart practices that are developed through diverse partnerships with scientists and practitioners are needed to decrease GHG emissions. We implemented

Isolation, identification, and the denitrification characteristics for a denitrifying strain: Paracoccus huijuniae

上海师范大学学报. 自然科学版
Nitrogen(N) removal become an important topic in municipal wastewater treatment, in which denitrification seems more important step. A denitrifying strain, Paracoccus huijuniae, was isolated and was employed for accelerating denitrification by means of ...

Weeds in a changing climate: Competitors or service plants?

PLANTS, PEOPLE, PLANET, EarlyView.
Reducing herbicide use and preparing agroecosystems for climate change are two top priorities on the global policy agenda. Here, we explore whether these two challenges can be tackled simultaneously. While weeds are generally considered a threat to crop production, we show that weeds can help overcome climate change challenges in agroecosystems ...

Optimization of Reaction Kinetic Model for Polymer Catalytic Reduction Denitrification

Journal of Chemistry
Polymer catalytic reduction (PCR) is a denitrification method that may exhibit higher efficiency and lower cost. However, the presence of catalysts in the PCR agent adds complexity to the denitrification reaction kinetics.

A novel aerobic-anoxic biological filter for nitrogen removal from UASB effluent using biogas compounds as electron donors for denitrification

Revista Facultad de Ingeniería Universidad de Antioquia, 2012
The performance of a new trickling filter (TF) configuration composed of an upper compartment for nitrification and a lower compartment for denitrification of effluent from a UASB reactor treating domestic sewage was evaluated.

Ecological Characteristics of Stream Reaches With and Without Low‐Tech Process‐Based Restoration in a Wildfire‐Affected Catchment

River Research and Applications, EarlyView.
ABSTRACT Low‐tech process‐based stream restoration (LTPBR) is increasingly implemented following wildfire, underscoring the need to evaluate restoration outcomes in burned catchments. To help address this need, we measured abiotic and biotic characteristics of a reach that received LTPBR, an untreated reach, and a reach with relict beaver activity that

Denitrification in Sinorhizobium meliloti

Biochemical Society Transactions, 2011
Denitrification is the complete reduction of nitrate or nitrite to N2, via the intermediates nitric oxide (NO) and nitrous oxide (N2O), and is coupled to energy conservation and growth under O2-limiting conditions. In Bradyrhizobium japonicum, this process occurs through the action of the napEDABC, nirK, norCBQD and nosRZDFYLX gene products.

Structure and functional genes associated with carbon, nitrogen, phosphorus, and sulfur cycling processes in periphyton: A comparison between natural and artificial rivers

River, EarlyView.
Network analysis of functional genes among prokaryotes, and eukaryotes in natural and artificial rivers. Abstract Periphyton in aquatic ecosystems plays vital roles in the elemental cycle process and is vulnerable to anthropogenic interference. However, few studies have explored the elemental cycles of carbon (C), nitrogen (N), phosphorus (P), and ...

Afforestation mitigates soil nitrogen limitation by enhancing mineralization and lowering denitrification in central China

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Afforestation has profoundly altered soil nitrogen (N) transformation, particularly the key processes governing soil organic N and inorganic N dynamics which determine soil N availability.

Nitrification amplifies the decreasing trends of atmospheric oxygen and implies a larger land carbon uptake [PDF]

, 2007
[1] Atmospheric O-2 trend measurements are used to partition global oceanic and land biotic carbon sinks on a multiannual basis. The underlying principle is that a terrestrial uptake or release of CO2 is accompanied by an opposite flux of O-2.
