Non-toxic total nitrogen determination using a low alkaline persulfate digestion

MethodsX, 2020
Measuring total nitrogen, nitrate, and nitrite is critical for compliance with water safety standards. Previous methods for measuring total nitrogen were hazardous, time consuming, and expensive.

Dissimilatory nitrogen reduction in intertidal sediments of a temperate estuary: small scale heterogeneity and novel nitrate-to-ammonium reducers [PDF]

, 2015
The estuarine nitrogen cycle can be substantially altered due to anthropogenic activities resulting in increased amounts of inorganic nitrogen (mainly nitrate).

Nitrite Reduction Assay for Whole Pseudomonas Cells

Bio-Protocol, 2016
The second step of the dissimilatory denitrification pathway in which nitrite (NO2-) is converted to nitric oxide (NO) is catalyzed by the enzyme nitrite reductase.

The nitric oxide response in plant-associated endosymbiotic bacteria [PDF]

, 2011
Nitric oxide (NO) is a gaseous signalling molecule which becomes very toxic due to its ability to react with multiple cellular targets in biological systems. Bacterial cells protect against NO through the expression of enzymes that detoxify this molecule

Identification and examination of nitrogen metabolic genes in Lelliottia amnigena PTJIIT1005 for their ability to perform nitrate remediation

BMC Genomics, 2023
Lelliottia amnigena PTJIIT1005 is a bacterium that utilizes nitrate as the sole nitrogen source and can remediate nitrate from media. The annotation was done related to nitrogen metabolic genes using the PATRIC, RAST tools, and PGAP from the genome ...

Bacterial nitrate assimilation: gene distribution and regulation [PDF]

, 2011
In the context of the global nitrogen cycle, the importance of inorganic nitrate for the nutrition and growth of marine and freshwater autotrophic phytoplankton has long been recognized.

Nitrite-Mediated Hypoxic Vasodilation Predicted from Mathematical Modeling and Quantified from in Vivo Studies in Rat Mesentery

Frontiers in Physiology, 2017
Nitric oxide (NO) generated from nitrite through nitrite reductase activity in red blood cells has been proposed to play a major role in hypoxic vasodilation.

Nitrite reductase activity and inhibition of H₂S biogenesis by human cystathionine ß-synthase. [PDF]

PLoS ONE, 2014
Nitrite was recognized as a potent vasodilator >130 years and has more recently emerged as an endogenous signaling molecule and modulator of gene expression. Understanding the molecular mechanisms that regulate nitrite metabolism is essential for its use

The key role of nitric oxide in hypoxia: hypoxic vasodilation and energy supply-demand matching [PDF]

, 2013
Significance: a mismatch between energy supply and demand induces tissue hypoxia with the potential to cause cell death and organ failure. Whenever arterial oxygen concentration is reduced, increases in blood flow - 'hypoxic vasodilation' - occur in an ...
