ABSTRACT
The abilities of Corynebacterium sp. RB-96, a strain isolated from petroleum- contaminated soil, to degrade crude oil of light and heavy type were investigated. The experiments were performed in liquid medium supplemented with each type of petroleum and in soils polluted with oil, too. The strain mineralized with preference light oil. The speed of biodegradation was higher in liquid medium in comparison with biooxidizing of petroleum in soil.
