摘要
      微生物燃料电池中抗生素的去除和ARGs的控制受到了广泛的关注。特别是生物电化学特性的关键作用值得进一步研究。生物电化学特性显著影响磺胺甲恶唑（SMX）的去除和ARGs的命运，其中电流强度比阳极电位起着更关键的作用。高浓度的SMX（2mg/L和10mg/L）有助于阳极电位趋于接近，因此，电流对系统的增强作用凸显出来。然而，在不同的生物电化学特性下，SMX的降解途径没有受到影响。此外，较高的电流强度比抗生素的去除更可取，但对ARGs的控制不利，这可能是由于微生物的氧化应激。低浓度SMX（0.5 mg/L）有助于提高发电量，因为地杆菌富集。这项研究表明，适当调节MFC的生物电化学特性对于去除抗生素和控制ARGs至关重要。
Abstract
Antibiotics removal and ARGs control in microbial fuel cell (MFC) has received extensive attention. In particular, the critical role of bioelectrochemical characteristics deserves further study. Bioelectrochemical characteristics significantly affected sulfamethoxazole (SMX) removal and ARGs fate, in which the current intensity played a more critical role than anode potential. High-concentration SMX (2 mg/L and 10 mg/L) facilitated the anode potential tend to be close, and thus, the strengthening effect of current on the system was highlighted. However, the SMX degradation pathway under different bioelectrochemical characteristics was not affected. Furthermore, the higher current intensity was preferable to antibiotic removal, but unfavorable for ARGs control might be due to the oxidative stress on microorganisms. Low-concentration SMX (0.5 mg/L) contributed to improving higher electricity generation because of Geobacter enrichement. This study suggested that appropriate bioelectrochemical characteristics regulation in MFCs was essential in removing antibiotics and controlling ARGs.
