摘要：
In this study carried out the bioremediation of a contaminated soil with a gasoline-diesel fuel mixture in a laboratory scale, to evaluate biostimulation against natural attenuation and bioaugmentation. The reduction of Total Petroleum Hydrocarbons (TPH) concentration during three months was 52.79 % for natural attenuation, 60.45 % for biostimulation and 64.92 % for bioaugmentation. For the inoculation in the bioaugmentation treatment, was isolated a bacterium with the capacity of degrade hydrocarbons which was identified as Bacillus sp.
