Abstract: Comamonas testosteroni is gram-negative, strict aerobes and frequently occurs in diverse habitats. It was named based on its ability to metabolize steroids. In recent years, it was found that Comamonas testosteroni strains are able to utilize many other kinds of environmental pollutants as sole carbon and energy sources. This review summarized the research advances on the bacterial biodegradation pathways of petroleum pollutants, such as polycyclic aromatic hydrocarbon, substituted aromatics, and heterocyclic aromatics; and the key enzymes and genes involved in the biodegradation pathways. It should provide a reference for the relevant microbial environmental pollution remediation.  
Key words: Comamonas testosteroni; petroleum pollutants; microbial biodegradation
