ABSTRACT
Our investigation was localized in the area of fuel base A of the former Soviet firing ground Borne Sulinowo, where petrol contamination of soils had been observed.
The suspenssion of yeast strain Yarrowia lipolytica A-101 was introduced into twelve one-metre deep bore-holes. The process of bioremediation was controlled using electromagnetic and resistivity methods, and microbial enumeration was done on Hy-Check slides. The measurements were carried out along the same profile in spring 2003, autumn 2003 and spring 2004. The significant increase of electrical conductivity of soils was observed in the vicinity of bore-holes with introduced yeast. The study showed the ability of Yarrowia lipolytica yeast to remedy petrol contaminated soils and the efficiency of applied geoelectrical methods to this process monitoring.
