Nitrite-driven anaerobic ethane oxidation
Environmental Science and EcotechnologyEthane, 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

Controls on nitrite oxidation in the upper Southern Ocean: insights from winter kinetics experiments in the Indian sector [PDF]
Biogeosciences, 2022 Across the Southern Ocean in winter, nitrification is the dominant mixed-layer nitrogen cycle process, with some of the nitrate produced therefrom persisting to fuel productivity during the subsequent growing season.

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 ...

Nitrite cycling in the primary nitrite maxima of the eastern tropical North Pacific [PDF]
Biogeosciences, 2023 The primary nitrite maximum (PNM) is a ubiquitous feature of the upper ocean, where nitrite accumulates in a sharp peak at the base of the euphotic zone.

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).

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

Nitroxyl Accelerates the Oxidation of Oxyhemoglobin by Nitrite [PDF]
Free Radical Biology and Medicine, 2011 Angeli's salt (Na₂N₂O₃) decomposes into nitroxyl (HNO) and nitrite (NO₂(-)), compounds of physiological and therapeutic interest for their impact on biological signaling both through nitric oxide and nitric oxide independent pathways. Both nitrite and HNO oxidize oxygenated hemoglobin to methemoglobin.

Cyclic Conversions in the Nitrogen Cycle
Frontiers in Microbiology, 2021 The cyclic nature of specific conversions in the nitrogen cycle imposes strict limitations to the conversions observed in nature and explains for example why anaerobic ammonium oxidation (anammox) bacteria can only use nitrite – and not nitrate – as ...
