Degradation of PBDEs by lignin peroxidase from white rot fungi Phanerochaete chrysosporium

摘要

1. Introduction As common flame-retardant used in diverse commercial products, polybrominated diphenyl ethers (PBDEs) are widely spread in the environment. The toxicity and estrogenicity of PBDEs have potentially threatened the whole ecosystem, especially the human beings. Previous researches on removal of PBDEs mainly focus on photochemical and anaerobic microbial degradation, recently, the aerobic fungi degradation and transformation of PBDEs was reported (e.g. white rot fungi). Lignin peroxidase (LiP) is an extracellular enzyme produced from certain species of white rot fungi when grown under nitrogen-limited conditions, which has been widely applied in lignin mineralization, decoloration of industrial dyestuff.
