·探究微生物推助的類芬頓反應降解四溴聯苯醚摘要多溴聯苯醚(Polybrominateddiphenylethers，簡稱PBDEs)幾十年來一直被用作阻燃劑，廣泛分布于土壤、水體、沉積物中。目前的研究表明，微生物推助的類芬頓反應（Fenton-likeReaction）可以自動產生羥基自由基(HO?)來降解四溴聯苯醚（BDE-47）。和傳統的（非生物）類芬頓反應比較，微生物推助的類芬頓反應的pH值與自然環境的pH值類似，并且不需要額外添加H2O2或使用UV射線就可以利用還原產生的Fe(II)作為反應物。BDE-47的降解過程是由實驗室內純培養的還原Fe（III）的兼性厭氧細菌，奧奈達希瓦氏菌(ShewancllaoneidensisMR-1)推動的。本研究以乳酸鈉為電子供體，水鐵礦、針鐵礦、檸檬酸鐵分別作為電子受體來培養兼性厭氧細菌S.oneidensisMR-1，結果表明，在相同條件下，通過8次厭氧好氧循環過程，在水鐵礦、針鐵礦、檸檬酸鐵中BDE-47分別被降解了83.99%，75.57%，67.74%。通過控制實驗條件，證明了驅動BDE-47降解的是羥基自由基(HO?)。微生物推助的類芬頓反應為能夠被羥基自由基(HO?)降解的環境污染物提供了一種新的發展途徑。關鍵詞：四溴聯苯醚；類芬頓反應；奧奈達希瓦氏菌；羥基自由基(HO?)
