Winter nitrification in ice-covered lakes.

PLoS ONE, 2019
With changes in ice cover duration, nutrient loading, and anoxia risk, it is important to understand the mechanisms that control nitrogen cycling and oxygen depletion in lakes through winter.

Contingent Effects of Liming on N2O-Emissions Driven by Autotrophic Nitrification

Frontiers in Environmental Science, 2020
Liming acidic soils is often found to reduce their N2O emission due to lowered N2O/(N2O + N2) product ratio of denitrification. Some field experiments have shown the opposite effect, however, and the reason for this could be that liming stimulates ...

Effects of Temperature and Humidity on Soil Gross Nitrogen Transformation in a Typical Shrub Ecosystem in Yanshan Mountain and Hilly Region

Life, 2023
Shrubland is a pivotal terrestrial ecosystem in China. Soil nitrogen transformations play a crucial role in maintaining the productivity of this ecosystem, yet the driving forces underlying it have not been sufficiently addressed, particularly under ...

Thermokinetics and gas emission characteristics of nitrification waste under different oxygen contents by using TG-FTIR technique

Case Studies in Thermal Engineering, 2023
Nitrification waste has been a main hazard factor in many fire and explosion accidents; however, its thermal characteristics, which provide critical information for hazard control, have not been extensively studied.

Changes in the Species and Functional Composition of Activated Sludge Communities Revealed Mechanisms of Partial Nitrification Established by Ultrasonication

Frontiers in Microbiology, 2022
To achieve energy-efficient shortcut nitrogen removal of wastewater in the future, selective elimination of nitrite-oxidizing bacteria (NOB) while enriching ammonia-oxidizing microorganisms is a crucial step. However, the underlying mechanisms of partial

High-throughput assays to identify archaea-targeting nitrification inhibitors

Frontiers in Plant Science
Nitrification is a microbial process that converts ammonia (NH3) to nitrite (NO2-) and then to nitrate (NO3-). The first and rate-limiting step in nitrification is ammonia oxidation, which is conducted by both bacteria and archaea.

Development of N2O emission factors derived from nitrification of treated sewage water in rivers

Water Science and Technology, 2023
Because treated sewage water contains nitrogen compounds such as NH4-N and NO2+3-N, nitrous oxide (N2O) which is one of the greenhouse gases is generated by nitrification and denitrification reactions in rivers.
