Denitrification contributes to N2O emission in paddy soils
Frontiers in Microbiology, 2023 Denitrification is vital to nitrogen removal and N2O release in ecosystems; in this regard, paddy soils exhibit strong denitrifying ability. However, the underlying mechanism of N2O emission from denitrification in paddy soils is yet to be elucidated. In

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Diesel vehicle‐derived NOx is a major pollutant, and NH3‐SCR with Cu‐SSZ‐13 is the mainstream abatement technology. In this study, vitamin C (Vc) was used as a crystal growth regulator to successfully synthesize Cu‐SSZ‐13‐Vc0.3 via the hydrothermal method. Experimental results demonstrate that the introduction of Vc significantly optimizes the

Stability and performance of two GSBR operated in alternating anoxic/aerobic or anaerobic/aerobic conditions for nutrient removal [PDF]
, 2012 Two granular sludge sequencing batch reactors (GSBR) with alternating anoxic/aerobic (R1) and anaerobic/aerobic (R2) conditions were operated with a 4-carbon-source synthetic influent. The physical properties of the granular sludge were very good (SVI≈20

Cereal Chemistry, EarlyView.ABSTRACT Background and Objectives Intermediate wheatgrass (IWG), a new perennial crop, is being explored for food applications; however, nitrogen application effects on its properties have not been investigated. This study evaluated the effects of applying 90 kg ha−1 of nitrogen in spring or fall seasons on the properties of IWG grown in Minnesota and

Nitric oxide and nitrous oxide production and cycling during dissimulatory nitrite reduction by Pseudomonas perfectomarina [PDF]
, 1989 The denitrifier Pseudomonas perfectomarina reduced nitrite under conditions of kinetic competition between cells and gas sparging for extracellular dissolved nitric and nitrous oxides, NOaq and N2Oaq, in a chemically defined marine medium.

Regulating Defect‐Coordinated Single‐Iron‐Atom Catalysts for Efficient Nitrate Reduction Reactions
Carbon Energy, EarlyView.This figure illustrates the ball‐and‐stick model of an asymmetric monatomic Fe─N2 catalyst and its catalytic process for converting nitrate to ammonia. Shown are the adsorption configurations of precursors and intermediates (NO3− → NO2− → NO → NH2OH → NH3) on the catalyst surface, where brown represents iron atoms, red represents oxygen atoms, dark ...

Denitrification in soil. II. Factors affecting denitrification
The Journal of Agricultural Science, 1958 1. The factors affecting denitrification in soil have been studied by determining loss of nitrogen from soil under various conditions by total-N analysis.2. It was found that the rate of denitrification of nitrate in soil was dependent upon various factors such as the pH, temperature and water content of the soil and that, under conditions conducive to

Dentrification potential of different landuse types in an agricultural watershed, lower Mississippi valley. [PDF]
, 2006 Expansion of agricultural land and excessive nitrogen (N) fertilizer use in the Mississippi River watershed has resulted in a three-fold increase in the nitrate load of the river since the early 1950s.
