In this paper, three bacteria strains were isolated from the soil and water polluted by crude oil and applied to degrate waste water. When 120 mg/L oily waste water was degraded by LSD-3,degrading rate of crude oil was up to 69% after 5 days.

• 从原油污染的土壤和水体中分离到3株高效原油降解菌；其中LSD-3在原油浓度为120mg/L的废水中；经过5d的培养；原油的降解率为69%25左右.
