Study on Extreme Microbial Degradation of Petroleum Hydrocarbons

Some oil-contaminated areas are often accompanied by extreme environments including high salinity, low temperature, and high temperature. The petroleum-degrading microorganisms isolated from these extreme environments can quickly adapt to extreme environments, grow and metabolize in extreme environments, and show great potential in the field of oil pollution control. This article reviews species, adaptation mechanism and research progress of oil-degrading bacteria in three extreme environments of hypersaline, low temperature and high temperature, so as to provide theoretical basis for further research and application.
