Genetics Advances in Upper Catabolic Pathways of Polycyclic Aromatic Hydrocarbons Degradation by Bacteria / 微生物学通报

ABSTRACT

Polycyclic aromatic hydrocarbons (PAHs) are widespread environmental pollutants with high toxicity. It is a potent way to remove these pollutions by microbe degradation and conversion, and many bacteria have been found performing this function. Here the bacterial catabolic enzymes and genes participating in upper pathway of PAHs degradation were revealed, the genetic properties were illuminated, and the gene evolution of PAHs catabolism was further discussed. It would contribute to elucidating PAHs degrading mechanisms in bacteria and provide theoretical evidence for achieving efficient bioremediation.
