摘要：

A phenanthrene degrading strain of Alcaligenes sp. was isolated from oil polluted soil. Addition of Alcaligenes sp. to soil microcosms supplemented with phenanthrene (1 mg/g dry soil) resulted in degradation of the added phenanthrene within 11 days. The phenanthrene concentration declined only 12% in uninoculated soil during 42 days. The total phenanthrene degradation potential of Alcaligenes sp. was 2.3 mg/g dry soil during a period of 22 days. The amount of CO2 evolved during 22 days corresponded to the conversion of 91% of the degraded phenanthrene to CO2. The Alcaligenes sp. were not able to degrade phenanthrene in sterile soil.
