Efeito da aplicação de nitrato na redução biogênica de sulfeto sob diferentes concentrações iniciais de bactérias redutoras de nitrato e sulfato Effect of nitrate application on reduction of biogenic sulphide under different initial concentrations of nitrate and sulphate-reducing bacteria

Química Nova, 2010
The effect of sodium nitrate application in the reduction of biogenic sulphide was evaluated through a 2k complete factorial design, using as variable response the production of sulfide at intervals of incubation of 7, 14 and 28 days.

Ruminal fermentation of Anti-methanogenic Nitrate- and Nitro-Containing Forages In Vitro

Frontiers in Veterinary Science, 2016
Nitrate, 3-nitro-1-propionic acid (NPA) and 3-nitro-1-propanol (NPOH) can accumulate in forages and be poisonous to animals if consumed in high enough amounts.
