Nitrate reduction

Not all inorganic salts are suitable as substrates for reduction reactions. Inorganic salts that can undergo reduction usually contain a central element in a relatively high oxidation state, such as N(+5) in NO₃⁻, S(+6) in SO₄²⁻, Cl(+7) in ClO₄⁻, Cr(+6) in CrO₄²⁻, as well as ...

Nitrate reduction is a key reaction in the biological nitrogen cycle that determines the fate of NO₃⁻. After NO₃⁻ is reduced to NO₂⁻, it can enter denitrification, DNRA, or assimilatory utilization pathways, which respectively affect nitrogen removal, nitrogen retention, and biomass ...

Nitrate reductase activity assays are used to analyze nitrate-reducing capacity in plant leaves, roots, algae, microorganisms, and soil samples. The core principle is to measure the rate at which NO₃⁻ is reduced to NO₂⁻. Common methods include in vitro enzyme extraction colorimetry, in ...
