Resumo: | To exploit the presence in the sea of microorganisms capable of degrading petroleum products a mineral fertilizer, containing immediatly assimilable nitrogen and phosphorus compounds, was used to increase the microbial population and therefore, the degradation potential of treated polluted waters. The fertilizer supply caused an increase in heterotrophic and hydrocarbon-splitting bacteria and an increase in the phytoplanktonic biomass. The latter is characterized by an increase in a few selected species; it constitutes an important supply of organic substances, and it is responsible for increasing the dissolved oxygen which is essential for petroleum oxidation. Supplying the fertilizer results in an increase in the treated water degradation potential and a faster chemical and physical evolution of the petroleum.
