The washing experiment of soil contaminated by petroleum alkane was performed with two kinds of biosurfactants in laboratory. The results showed that biosurfactant would enhance on removal of residual alkane in soil, after washing with 20 pore volume solution the removal rate with BS-UC and MELs were three times and twice as that of water, respectively.

在实验室内对南极假丝酵母产生的两种生物表面活性剂进行了石油烃类污染土壤的冲洗实验，结果表明，经过大约20个孔隙体积的冲洗，BS-UC溶液的除油率为清水的三倍，MEL溶液为清水的两倍，这表明该生物表面活性剂能够加速土壤残油的去除，而来自污染底物的生物表面活性剂更具有优越性。
