Abstract: Petroleum hydrocarbon contaminants are complex organic compounds, and it would cause great risk to the ecological environment and public health. Currently, microbial technology becomes a popular remediation technology for petroleum hydrocarbon contaminations. Microorganisms use the pollutants as a carbon source and metabolize and degrade it through a series of enzymatic catalysis. For increasing the application of microbial remediation of petroleum hydrocarbon pollution, the method of rational design of enzymes at key steps can be used to increase the microbial degradation rates of petroleum hydrocarbons. This review summarizes the main components and structures of petroleum hydrocarbons, metabolic pathways, functional genes and key enzyme types, as well as the application status of omics and synthetic biology technologies in the research of petroleum hydrocarbon degradation and metabolism mechanism, providing a reference for further improving the application prospects of microbial remediation technology in the field of petroleum hydrocarbon pollution.
