Isoform-Specific NO Synthesis by Arabidopsis thaliana Nitrate Reductase

open access: yesPlants, 2019
Nitrate reductase (NR) is important for higher land plants, as it catalyzes the rate-limiting step in the nitrate assimilation pathway, the two-electron reduction of nitrate to nitrite.

Efficiency of microalgae cultures for nutrient removal from domestic wastewater [PDF]

open access: yesAdvances in Environmental Technology, 2022
Domestic wastewaters are one of the main sources of contamination and diseases. However, they can be treated and potentially reused if certain organic and inorganic compounds and molecules are eliminated.

Photochemical production and evolution of selected C2-C5 alkyl nitrates in tropospheric air influenced by Asian outflow [PDF]

open access: yes, 2003
The photochemical production and evolution of six C2-C5 alkyl nitrates (ethyl-, 1-propyl-, 2-propyl-, 2-butyl-, 2-pentyl-, and 3-pentyl nitrate) was investigated using selected data from 5500 whole air samples collected downwind of Asia during the ...

Adsorption of Nitrate by a Novel Polyacrylic Anion Exchange Resin from Water with Dissolved Organic Matters: Batch and Column Study

open access: yesApplied Sciences, 2019
A novel anion exchange resin AEE-3 was synthesized by N-alkylation of a weakly basic polyacrylic anion exchanger D311 with 1-bromopropane to effectively remove nitrate (NO3−-N) from aqueous solution. The related finding revealed that its adsorption

Comparison of nitrification inhibitors to restrict nitrate leaching in a maize crop irrigated under mediterranean conditions [PDF]

open access: yes, 2010
The aim of this paper was to compare dicyandiamide (DCD) and 3,4 dimethylpyrazole phosphate (DMPP) as inhibitors of ammonium oxidation and nitrate leaching after applying fertilizer to a maize (Zea mays L.) crop grown under Mediterranean conditions.

Quantitative aspects of nitric oxide production from nitrate and nitrite

open access: yesEXCLI Journal : Experimental and Clinical Sciences, 2022
Nitric oxide (NO) is involved in many physiological and pathological processes in the human body. At least two major pathways produce NO: (1) the L-arginine-NO-oxidative pathway in which NO synthase (NOS) enzymes convert L-arginine to NO; (2) the nitrate-
