多环芳烃是化石燃料不完全燃烧的产物，在自然界中普遍存在。其中一些化学品具有遗传毒性和致癌潜力，而且在环境中具有持久性，因此引起环境关注。在过去的几十年里，许多研究人员都集中在这些污染物的生物降解。生物修复技术已被开发出来，用于清理受污染的土壤。更好地了解多环芳烃降解微生物的代谢、酶机制和遗传学对于优化这些生物修复过程至关重要。
Polycyclic aromatic hydrocarbons, the products of the incomplete combustion of fossil fuels, are ubiquitous in nature. Some of these chemicals are of environmental concern because of their genotoxic and carcinogenic potential and their persistence in the environment. Over the last few decades, many investigators have focused on the biodegradation of these pollutants. Bioremediation technologies have been developed to clean up contaminated soils. A better understanding of the metabolism, enzyme mechanisms, and genetics of polycyclic aromatic hydrocarbon degrading microorganisms is critical for the optimization of these bioremediation processes.
