Abstract The scope of this research is to perform bioremediation of historically polluted, multiple fraction soil with glycolipid-based anionic biosurfactants. The aim is to optimize the conditions for ex situ soil washing by involving statistical data analysis tools for experimental data. The quadratic interaction model shows that the most influential process parameter at a 95.0 % confidence level was observed for the biosurfactant concentration variable. The results of the study proved the potential for applications of “plate” tests for the formulation of new soil washing products and for the selection of proper biosurfactants for the problem under study.
