石油污染土壤的生物降解研究

Biodeyradation has the characteristics of simple operation,low cost,and easy application.In this research,two fungus were chosen to degrade the oil in polluted soil in laboratory and fields.In the laboratory culture test with temperature controlled,the rate of oil degradation by native fungi (F) and foreign fungi (P) are 61.8% and 66.1% respectively after 50 days.In the field test the rate of oil degradation by native fungi (F) and foreign fungi (P) are 59.8% and 70.1% respectively after 150 days.
