Abstract:

Oil pollution in polar ocean increases with the exploration and utilization of polar area.And oil degradation in polar area is very slow for perennially low temperature there.Biodegradation is a major mechanism of oil degradation from the environment for its economic and effective characters.There are a lot of hydrocarbon-degrading microbes in polar ocean.They play an important role in eliminating oil pollution,and show the potential for bioremediation in low temperature.In this paper,we outline the status of research in areas of oil biodegradation in polar ocean and introduce the hydrocarbon-degrading microbes in polar ocean,factors influencing low temperature biodegradation,biodegradation genes and bioremediation in low temperature.
