It is controversial to introduce oxygen into anode chamber as oxygen would decrease the CE (Coulombic efficiency) while it could also enhance the degradation of aromatics in microbial fuel cell (MFCs). Therefore, it is important to balance the pros and cons of oxygen in aromatics driven MFCs. A R_MO (micro-oxygen bioanode MFC) was designed to determine the effect of oxygen on electricity output and phenol degradation. The R_MO showed 6-fold higher phenol removal efficiency, 4-fold higher current generation than the R_AN (anaerobic bioanode MFC) at a cost of 26.9% decline in CE. The Zoogloea and Geobacter, which account for phenol degradation and current generation, respectively, were dominated in the R_MO bioanode biofilm. The biomass also showed great difference between R_MO and R_AN (114.3 ± 14.1 vs. 2.2 ± 0.5 nmol/g). Therefore, different microbial community, higher biomass as well as the different degradation pathway were suggested as reasons for the better performance in R_MO.

将氧气引入阳极室是有争议的，因为氧气会降低CE（库仑效率），同时也会增强微生物燃料电池（MFCs）中芳烃的降解。因此，重要的是平衡芳族化合物驱动的MFC中氧气的利弊。设计了AR _MO（微氧生物阳极MFC）来确定氧气对电力输出和苯酚降解的影响。R _MO显示出比R _AN（厌氧生物阳极MFC）高6倍的苯酚去除效率，高4倍的电流生成，而CE降低了26.9％。在菌胶团和地杆菌，分别解释了苯酚降解和电流产生，在R _MO生物阳极生物膜中占主导地位。生物量也显示出R _MO和R _AN之间的巨大差异（114.3±14.1 vs. 2.2±0.5 nmol / g）。因此，不同的微生物群落，更高的生物量以及不同的降解途径被认为是R _MO性能更好的原因。
