Abstract: Samples of soil contaminated with diesel oil were taken near a petroleum refinery in Campinas, Brazil, and employed to isolate microorganisms. Six bacteria were chosen and identified, and their emulsification activities were evaluated after growth on 3%, 5%, 15% or 30% of diesel oil. The bacterial strains Actinobacillus lignieresii, Moraxella nonliquefaciens, Acinetobacter calcoaceticus and Flavobacterium sp had high emulsification activities after growth for 120 hr in all the concentrations of diesel oil used. Bacillus megaterium created oil-in-water emulsions after 120-hr growth only at the diesel oil concentration of 1.5%. Planococcus citreus emulsified all of the diesel oil present in the growth medium, regardless of the concentrations and of the incubation period. No emulsification activities were found in its culture supernatants.
