Abstract
Microbially mediated reductive dechlorination of polychlorinated biphenyls (PCBs) in anaerobic sediments has been observed during laboratory experiments. Reductive dechlorination is a two-electron transfer reaction which involves the release of chlorine as a chloride ion and its replacement on the aromatic ring by hydrogen. The exact mechanism of the electron transfer for PCBs is unknown; however, this work shows that the source of the hydrogen atom is the proton (H) from water.
摘要
在实验室实验中观察到了微生物介导的多氯联苯 (PCBs) 在厌氧沉积物中的还原脱氯。还原脱氯是涉及释放氯作为氯离子并由氢取代芳环上的氯的两电子转移反应。对于 PCB 的电子转移的确切机制尚不清楚；然而，这项工作表明氢原子的来源是来自水的质子 (H)。
