The effect of sodium nitrate application in the reduction of biogenic sulphide was evaluated through a 2 k complete factorial design, using as variable response the production of sulfide at intervals of incubation of 7, 14 and 28 days. The most effective condition for reducing the sulphide production (final concentrations from 0.4 to 1.6 mg S 2-L -1 ) was obtained with an initial population of sulphate-reducing bacteria and nitrate-reducing bacteria of 10 4 MPN mL -1 and 427.5 mg L -1 nitrate.
