摘要
With wide application of fossil fuels, polycyclic aromatic hydrocarbon caused pollution has been becoming a serious problem. In order to improve the degradation ability of wild-type bacteria in biological treatment of polycyclic aromatic hydrocarbon, a strain of high-efficient phenanthrene degrading bacteria is isolated and purified from a long-term oil-contaminated site of a petrochemical company in Beijing. It is identified as maltophilic oligotrophomonas, and its strain evolutionary tree is drawn out.A genetically stable and highly efficient degrading strain is obtained by means of nitrogen ion mutagenesis and plasma mutagenesis at normal temperature, and is used to treat with 100 mg•L-1 phenanthrene.It is found that phenanthrene has been degraded by about 64% in 3 days, and has been almost fully degraded after 5 days.
