Nitrite-driven anaerobic ethane oxidation

Environmental Science and Ecotechnology
Ethane, the second most abundant gaseous hydrocarbon in vast anoxic environments, is an overlooked greenhouse gas. Microbial anaerobic oxidation of ethane can be driven by available electron acceptors such as sulfate and nitrate. However, despite nitrite

Evaluating nitrite oxidizing organism survival under different nitrite concentrations [PDF]

Water Science and Technology, 2020
Abstract The objective of this study is to explore the optimal pre-treatment procedures and statistics methods for live/dead bacterial staining using nitrite oxidizing organism (NOO) as the research aim. This staining method was developed and widely utilized to evaluate activated bacterial survival situation, because it is direct and ...

Nitrite-oxidizing bacteria adapted to low-oxygen conditions dominate nitrite oxidation in marine oxygen minimum zones. [PDF]

ISME J
Abstract Nitrite is a central molecule in the nitrogen cycle because nitrite oxidation to nitrate (an aerobic process) retains fixed nitrogen in a system and its reduction to dinitrogen gas (anaerobic) reduces the fixed nitrogen inventory.

Nitric oxide preferentially inhibits nitrite oxidizing communities with high affinity for nitrite [PDF]

Journal of Biotechnology, 2015
The prerequisite to the development success of the novel mainstream processes partial nitritation/anammox is the out-selection of nitrite oxidizing bacteria (NOB). A recent study suggested that this could be achieved through NO production by ammonium oxidizing bacteria under cyclic oxic-anoxic conditions. Indeed, it is known that among NOB, Nitrobacter

Nitrite-oxidizing activity responds to nitrite accumulation in soil [PDF]

FEMS Microbiology Ecology, 2018
The factors influencing how soil nitrite (NO2-)- and ammonia (NH3)-oxidizing activities remain coupled are unknown. A short-term study (

Effect of pH and nitrite concentration on nitrite oxidation rate [PDF]

Bioresource Technology, 2011
The effect of pH and nitrite concentration on the activity of the nitrite oxidizing bacteria (NOB) in an activated sludge reactor has been determined by means of laboratory batch experiments based on respirometric techniques. The bacterial activity was measured at different pH and at different total nitrite concentrations (TNO₂).

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 ...

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

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.

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
