Biofilm-mediated bioremediation presents a proficient alternative to bioremediation with planktonic microorganisms and are generally associated with microbial hydrocarbons resistance or tolerance. Changes in biofilm formation and siderophores production were monitored in the presence of different concentrations of benzene and xylene. All strains were able to synthesize biosurfactant compounds and were able to tolerate aromatic hydrocarbon more than the cyclic compounds. Our results indicated that hydrocarbon mixture or gasoline could be better biodegraded by bacterial consortia; P. aeruginosa exhibited the best tolerance to gasoline but not to benzene and cyclohexane. It is interesting to point out that P. fluorescens was able to use xylene and benzene even though P. putida was incapable to grow on benzene as a carbon source. Statistically no significant positive correlation between biofilm formation and surface tension, whereas with E24 and cells hydrophobicity we signaled a linear negative relationship.
