The interspecies electron transfer (IET) between archaea and bacteria is the key to higher COD/CO₂ conversion, resulting in higher energy generated by the MFC. This study finds that the application of magnetite-nanoparticles and static magnetic field on a MFC in anaerobic digestion enhances electrical conductivity and magnetic field, which decreases the resistance that protons (H⁺) and ions encounter as they flow inside the MFC. This accelerates the syntrophy action by IET, resulting in higher bacterial degradation, biogas generation, and decontamination.

磁铁矿纳米粒子和静磁场在微生物燃料电池厌氧消化中的应用

古细菌和细菌之间的种间电子转移 (IET)是提高 COD/CO ₂转化率的关键，从而导致 MFC 产生更高的能量。^{这项研究发现，在厌氧消化的 MFC 上应用磁铁矿纳米粒子和静磁场增强了电导率和磁场，从而降低了质子 (H +} ) 和离子在 MFC 内流动时遇到的阻力。这加速了 IET 的协同作用，导致更高的细菌降解、沼气产生和净化。
