Nitrification and growth of autotrophic nitrifying bacteria and Thaumarchaeota in the coastal North Sea [PDF]

open access: yesBiogeosciences, 2013
Nitrification and the associated growth of autotrophic nitrifiers, as well as the contributions of bacteria and Thaumarchaeota to total autotrophic C-fixation by nitrifiers were investigated in the Dutch coastal North Sea from October 2007 to March 2008.

Winter nitrification in ice-covered lakes.

open access: yesPLoS 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.

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

open access: yesFrontiers 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 ...

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

open access: yesFrontiers 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 ...

Trace Elements and Nitrification

open access: yesNature, 1948
THE exact requirements of the nitrifying bacteria for inorganic nutrients are not yet known, though all workers on this group since Winogradsky1 have assumed that they require iron, and many workers have added traces of other metals to their media2, or used tap-water as a diluent, because of the possible trace elements it contains3.

High-throughput assays to identify archaea-targeting nitrification inhibitors

open access: yesFrontiers 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.

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

open access: yesFrontiers 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
