Immobilized microorganism systems have the potential to degrade toxic chemicals faster than conventional treatment systems. Based on an effective hydrocarbon-degrading bacterial strain which was isolated from oil-contaminated soil of Dagang Oilfield, this study investigated the optimum preparation of immobilized microorganism: sodium alginate 2.5-3.5%, attapulgite clay 0.5-1.5%, CaCl2 2-4% In terms of percentage removal of petroleum hydrocarbon after 15 days, petroleum hydrocarbon degradation was obviously enhanced when the bacteria were immobilized and scanning electron micrographs demonstrated good macroporous structure for mass transfer of substrate and immobilized cell growth.
