門玉潔博士是加州大學河濱分校的助理教授。她獲得了加州大學伯克利分校的土木與環(huán)境工程博士學位和清華大學的環(huán)境工程碩士。她的專長包括環(huán)境微生物學、微生物生態(tài)學和分析化學。她的研究興趣集中在微生物與受新興關注污染物 (CEC) 影響的環(huán)境之間的相互作用,例如,CEC 的生物轉化,特別是全氟和多氟烷基物質,以及 CEC 對環(huán)境微生物功能的影響 ,包括抗生素耐藥性的發(fā)展和傳播。
報告摘要
Carbon-fluorine (C–F) bond is the strongest single bond in nature. Per- and polyfluoroalkyl substances (PFAS) are a large group of man-made chemicals with broad applications causing severe environmental concerns due to their persistence and toxicity. Although microbial defluorination of naturally occurring and less fluorinated compounds, such as monofluoroacetate, has been well studied, biodefluorination pathways and mechanisms of highly fluorinated PFAS have not been clearly understood. An introduction of the current research status of microbial defluorination will be given first, followed by the most recent findings on microbial defluorination of a variety of per- and polyfluorinated compounds, defluorination pathway elucidation, and the identification of responsible microorganisms.
