  • Biological treatment of wastewater using glucose and oil as the sole carbon source, respectively by immobilized yeast Yarrowia lipolytica were studied. Under the optimum conditions, the removal rates of salad oil and COD attained above 80%, when concentrations of oil and COD were 2 000 mg/L.The degradation efficiency of salad oil and COD by immobilized cells increased with the extending of time, at the same time, decreased with the increasing of density of substrate. Results further showed that immobilized cells had higher storage stability and reusability than freesuspended cells. These results suggested that immobilized Yarrowia lipolytica might be applied to treat oily wastewater and sewage with high concentrations of COD.
