The application of this fermentation system is remediation of soil, contaminated with oil over a long period. In this system bacteria consortium have been cultivated, which has been isolated from oil-contaminated soil.

Fermentation system consists of 30, 100 and 800 liter bioreactors. Another 800 liter reactor is used for storage of a substrate. In every bioreactor is temperature, pH, pO2, foam and level control, as well as time profiles of automatic substrate feeding rate can be adjusted. The sterilization possibility of all fermentation system including pipelines is ensured.
