View ArticleBiodegradation in residual basaltic soil contaminated by diesel fuel and biodiesel was assessed by three different techniques comprising natural attenuation, bioaugmentation, and bioventing. The soil was described in terms of its
physicochemical and microbiological characteristics, showing favorable bioremediation conditions. Natural attenua...
