Bacterial preparations for degradation of petroleum products in soil

Bioremediation seems not only to be a very economically competitive but also an ecologically sound remediation technology. The aim of this work was to evaluate the possibility of enhancement of the natural bioremediation process by inoculating soil with strains actively degrading oil. The field experiments were carried out by ex situ method during summer for 3 months. The process efficiency was very high and petroleum product concentration levels in soil were reduced by several dozens of mg per 1 kg dry matter of soil.
