Development of a stoichiometric model of the sulphate-reduction by the sulphate-reducing bacteria in anaerobic lagoons. One of the most known disadvantages of the technique of lagoon is the generation of smells, often associated with the presence of hydrogen sulfide (H(2)S), itself generated by the process of sulfate-reduction. In this paper, we have built a stoichiometric model of sulfate-reduction by providing balanced equations against the elements, electrons, charge and energy. In our model, sulfate acts as an electron acceptor and organic compounds such as lactate, propionate, butyrate, ethanol and acetate are in turn sources of carbon and electron donors. This model allows to quantify the production of sulfide and predicts the variation of alkalinity during the process of sulfate-reduction.
