AbstractObjective: Biosurfactants are surface-active substances produced by microorganisms. The growth of microorganism supports biosurfactant production on hydrocarbon polluted environments. In this study, the capacity of biosurfactant production of Georgenia daeguensis (accession number, KP798810) isolated from hydrocarbon- contaminated soil was studied.Methods: The components of biosurfactant production medium were investigated through Plackett-Burman methodology. By using Placket-Burman based on statistical screening, six of the eleven factors of production medium were found to be critically effective on the biosurfactant production.Results: The significant factors were KCl, ZnSOConclusion: This study reported that Georgenia daeguensis is able to produce effective biosurfactant exhibiting antibacterial activity against K. pneumoniae.

In this paper, Fenton oxidation technology was used for oxidation treatment of soil contaminated by heavy oil, and environmental conditions were investigated for improving the effect of Fenton oxidation. The results showed that under the direct sunlight, liquid to soil was 2:1, pH was 5, 10.0mL 18 mmol•L-1 Fe2+ and 10.0mL 30%H2O2 were added to 1000g soil contaminated by heavy oil which contained 8% petroleum hydrocarbons, the petroleum hydrocarbons reduced from 5.74% to 2.92%.
