Kinetics of Indigenous Isolated Bacteria used for Ex-Situ Bioremediation of Petroleum Contaminated Soil
2008
Abbassi, Bassim E. | Shquirat, Walid D.
The bioremediation of petroleum contaminated soil was investigated using a laboratory scale aerated reactor. The Indigenous bacteria, Stenotrophomonas multophilia, were isolated from the contaminated sites near to Jordan Petroleum Refinery and used further in the bioremediation experiments. First order kinetic equation has been proven to satisfactorily describe the biodegradation of petroleum contained in soil in the presence of the isolated bacteria. The results also showed that the first order kinetic constants for the different bioreactors vary between 0.041 and 0.0071/day. The overall kinetic constant k' was determined based on food-to-microorganisms ratio and found to be 0.02/day.
