...反应均为放热反应，所以在无氧或缺氧条件下，细菌可以将硝酸盐作为电子传递链的最终电子受体（TEA, terminal electron acceptor），来完成物质能量交换。
双语例句
1
In the process of sulfide mineral bio-oxidization, molecular oxygen is the terminalelectronacceptor. As a result, there must be a sufficient oxygen supply.
分子氧是硫化矿物生物氧化过程中电子转移的最终受体，因此硫化矿物的生物氧化过程必须供氧。
2
Redox mediators can accelerate the electron transfer from a primary electron donor to a terminalelectronacceptor, which may increase the reaction rates by one to several orders of magnitude.
