Comparison of Oxidation Kinetics of Nitrite-Oxidizing Bacteria: Nitrite Availability as a Key Factor in Niche Differentiation [PDF]
Applied and Environmental Microbiology, 2015 ABSTRACT Nitrification has an immense impact on nitrogen cycling in natural ecosystems and in wastewater treatment plants. Mathematical models function as tools to capture the complexity of these biological systems, but kinetic parameters especially of nitrite-oxidizing bacteria (NOB) are lacking because of a limited number of ...

Nitrogen removal in marine environments: recent findings and future research challenges [PDF]
, 2005 Respiratory reduction of nitrate (denitrification) is recognized as the most important process converting biologically available (fixed) nitrogen to N2. In current N cycle models, a major proportion of global marine denitrification (50–70%) is assumed to

Betanin inhibits the myeloperoxidase/nitrite-induced oxidation of human low-density lipoproteins [PDF]
, 2007 Production of nitrogen dioxide by the activity of myeloperoxidase (MPO) in the presence of nitrite is now considered a key step in the pathophysiology of low-density lipoprotein (LDL) oxidation.

Evaluating two concepts for the modelling of intermediates accumulation during biological denitrification in wastewater treatment [PDF]
, 2015 The accumulation of the denitrification intermediates in wastewater treatment systems is highly undesirable, since both nitrite and nitric oxide (NO) are known to be toxic to bacteria, and nitrous oxide (N2O) is a potent greenhouse gas and an ozone ...

Dissimilatory Nitrite and Nitric Oxide Reductases [PDF]
Chemical Reviews, 1996 The inorganic nitrogen cycle (Figure 1) consists of several linked biological processes and one abiological process, the reaction of N2 and O2 in lightning discharges and internal combustion engines to produce NOx and, ultimately, nitrate. All of the processes except nitrogen fixation involve reduction or oxidation of species containing N-O bonds of ...

Forecasting wind speed data by using a combination of ARIMA model with single exponential smoothing [PDF]
, 2021 Wind serves as natural resources as the solution to minimize global warming and has been commonly used to produce electricity. Because of their uncontrollable wind characteristics, wind speed forecasting is considered one of the best challenges in ...
