GOMEZ, WILMAR; GAVIRIA, JAIR e CARDONA, SANTIAGO. ASSESSMENT OF THE BIOSTIMULATION AGAINST BIOAUGMENTATION AND NATURAL ATTENUATION ON CONTAMINATED SOIL WITH DIESEL-GASOLINE MIXING. Dyna rev.fac.nac.minas [online]. 2009, vol.76, n.160, pp.83-93. ISSN 0012-7353.
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.
