Nitrate ammonification is important for soil nitrogen retention. However, the ecology of ammonifiers and their prevalence compared with denitrifiers, being competitors for nitrate, are overlooked.

Woodchip bioreactors are increasingly used to remove nitrate (NO3–) from agricultural drainage water in order to protect aquatic ecosystems from excess nitrogen. Nitrate removal in woodchip bioreactors is based on microbial processes, but the microbiomes

Nitrate-reducing iron(II) oxidation (NRFO) has been intensively reported in various bacteria. Iron(II) oxidation is found to be involved in both enzymatic and chemical reactions in nitrate-reducing Fe(II)-oxidizing microorganisms (NRFOMs).

Characteristics of a Nitrate Reductase in a Barley Mutant Deficient in NADH Nitrate Reductase [PDF]
A barley (Hordeum vulgare L.) mutant, nar1a (formerly Az12), deficient in NADH nitrate reductase activity is, nevertheless, capable of growth with nitrate as the sole nitrogen source. In an attempt to identify the mechanism(s) of nitrate reduction in the mutant, nitrate reductase from nar1a was characterized to determine whether the residual activity ...

Rhizobium etli Produces Nitrous Oxide by Coupling the Assimilatory and Denitrification Pathways
More than two-thirds of the powerful greenhouse gas nitrous oxide (N2O) emissions from soils can be attributed to microbial denitrification and nitrification processes.

Although the nitrate assimilation into amino acids in photosynthetic leaf tissues is active under the light, the studies during 1950s and 1970s in the dark nitrate assimilation provided fragmental and variable activities, and the mechanism of reductant ...

Cloning and nitrate induction of nitrate reductase mRNA [PDF]
Nitrate is the major source of nitrogen taken from the soil by higher plants but requires reduction to ammonia prior to incorporation into amino acids. The first enzyme in the reducing pathway is a nitrate-inducible enzyme, nitrate reductase (EC 1.6.6.1).

Nitrate Reductase mRNA Regulation in Nicotiana plumbaginifolia Nitrate Reductase-Deficient Mutants [PDF]
Light and substrate regulation of nitrate reductase (NR) expression were compared in wild type and mutant lines of Nicotiana plumbaginifolia. Mutants affected in the NR structural gene (nia) or in the biosynthesis of the NR molybdenum cofactor (cnx) were examined.

Nitrates, such as cardiac therapeutics and food additives, are common headache triggers, with nitric oxide playing an important role. Facultative anaerobic bacteria in the oral cavity may contribute migraine-triggering levels of nitric oxide through the ...
