Microbiology of a Nitrite-Oxidizing Bioreactor [PDF]

Applied and Environmental Microbiology, 1998
ABSTRACT The microbiology of the biomass from a nitrite-oxidizing sequencing batch reactor (NOSBR) fed with an inorganic salts solution and nitrite as the sole energy source that had been operating for 6 months was investigated by microscopy, by culture-dependent methods, and by molecular biological methods, and the seed sludge ...

Metal Nitrite: A Powerful Oxidizing Reagent [PDF]

Journal of the American Chemical Society, 2011
An efficient and simple source of nitroso reagents and their oxidation reactions are described. The combination of a Lewis acid and a metal nitrite was applied to the oxidation of silyl enol ethers. Amino acid and peptide derivatives were easily accessed through in situ C-C bond cleavage of fully substituted silyl enol ethers upon oxidation.

Kinetic plasticity of nitrite-oxidizing bacteria containing cytoplasmic nitrite oxidoreductase. [PDF]

ISME J
Abstract Nitrite oxidation, the second step of nitrification, is essential to the global nitrogen cycle. Nitrite-oxidizing bacteria (NOB) are classified into two groups based on the cellular localization of their key enzyme nitrite oxidoreductase (NXR): periplasmic (pNXR) and cytoplasmic (cNXR). The use of a cNXR by NOB has been reported to

Response of Maximum Cell-Specific Nitrite Oxidation Rate to Hysteresis of Nitrite Oxidation by Nitrite-Oxidation Bacteria

Journal of Japan Society on Water Environment, 2008
A factor that controls maximum cell-specific nitrite oxidation rate was examined using the enrichment culture of Nitrobacter. Increasing or decreasing nitrite loading changed the content of Q-10, which served as a hydrogen carrier in the electron transport chain of Nitrobacter, which varied the maximum cell-specific nitrite oxidation rate. That is, the

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 ...

Evaluation of Non-Biodegradable Organic Matter and Microbial Community’s Effects on Achievement of Partial Nitrification Coupled with ANAMMOX for Treating Low-Carbon Livestock Wastewater

Applied Sciences, 2022
After the anaerobic digestion of livestock manure, high concentrations of nutrients still remain. Treatment of livestock wastewater through partial nitrification coupled with anaerobic ammonium oxidation (ANAMMOX) could be a useful technology depending ...

Niche differentiation in nitrogen metabolism among methanotrophs within an operational taxonomic unit [PDF]

, 2014
Background: The currently accepted thesis on nitrogenous fertilizer additions on methane oxidation activity assumes niche partitioning among methanotrophic species, with activity responses to changes in nitrogen content being dependent on the in situ ...

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 ...
