Evaluation of Plant–Microorganism Synergy for the Remediation of Diesel Fuel Contaminated Soil.

The remediation of diesel fuel contaminated soil over a 2-year period by the plant–microorganism synergy was evaluated. Results indicated that the growth of Astragalus adsurgens was affected significantly, when the diesel fuel concentration was higher than 10 g kg⁻¹ dry soil. After a 2-year period, the removal of diesel fuel was >67%, and about 58–70% removal of aromatic hydrocarbons was obtained in these treatments. The removal of diesel fuel and its components was 13–30% higher than that of plant alone. These results show that an appropriate plant–microorganism synergy may serve as a low-cost, effective remedial technology for diesel-contaminated soil. [ABSTRACT FROM AUTHOR]
