摘要

The process of biodegradation of soils contaminated by animal (raw fish oil) and mineral (toluene) origin compounds was studied, verifying the influence of adding biosurfactants and chemical surfactants and nutrients in the media. The highest removal rate of fish oil was 59.47% obtained in the experiments containing biosurfactant and biostimulate in 90 days process. The highest removal rate of toluene was achieved in 14 days for experiments containing biosurfactant, chemical spreading and biosurfactant with biostimulation, showing great influence of evaporation on the process. The use of surfactants has shown to increase the contaminant bioavailability due to its higher degradation rate.
