Effect of pH on nitrification

浙江大学学报. 农业与生命科学版, 2005
Nitrification is an effective technology to control nitrogen pollution from wastewater. The effect of pH on nitrification and the relationship between pH and alkalinity were analyzed.

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

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.

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.

Nitrification Rates Are Affected by Biogenic Nitrate and Volatile Organic Compounds in Agricultural Soils

Frontiers in Microbiology, 2019
The processes regulating nitrification in soils are not entirely understood. Here we provide evidence that nitrification rates in soil may be affected by complexed nitrate molecules and microbial volatile organic compounds (mVOCs) produced during ...

Effects of the Fluid Replacement Method During Online Hemodiafiltration on the Solute Removal Performance and Biocompatibility Using the Asymmetric Cellulose Triacetate Membrane

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Pre‐dilution online hemodiafiltration (Pre‐HDF) is predominantly used in Japan, whereas post‐dilution online HDF (Post‐HDF) is more common in Europe. An asymmetric cellulose triacetate (ATA) membrane may improve biocompatibility.

Heterotrophic nitrification of organic nitrogen is stimulated by agricultural plants

Communications Earth & Environment
The association between soil heterotrophic nitrification and plant nitrogen (N) uptake remains poorly understood. Here, we used 15N isotope tracing and numerical analysis to quantify the rate of ammonification (organic N to ammonium), heterotrophic ...

Relative Abundance of Ammonia Oxidizing Archaea and Bacteria Influences Soil Nitrification Responses to Temperature

Microorganisms, 2019
Ammonia oxidizing archaea (AOA) and bacteria (AOB) are thought to contribute differently to soil nitrification, yet the extent to which their relative abundances influence the temperature response of nitrification is poorly understood.

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.
