The adverse effect of tetracycline antibiotics on microbial activity is one of the serious risks for the biologic wastewater treatment process. The microbial fuel cells (MFCs) are a promising technology for wastewater treatment and renewable power generation process. For this reason, the investigation of the inhibition effect of the tetracyclines on the MFCs is essential for reducing damage on the environment. This paper focused on the performance of MFCs under different antibiotic concentrations at the range of 0.25-50 mg/L. The power generation performance, microbial community and biofilm characteristics (morphology, resistance and viability) of MFCs were investigated in detail. The results indicated that the increase in the antibiotic concentration significantly affected the MFC performance and microbial community. A modified non-competitive inhibition model was used to predict the inhibition effect of tetracycline antibiotics on the MFCs.
四环素类抗生素对微生物活性的不利影响是生物废水处理过程的严重风险之一。微生物燃料电池（MFC）是一种很有前途的废水处理和可再生发电技术。出于这个原因，研究四环素类抗生素对 MFC 的抑制作用对于减少对环境的破坏至关重要。本文重点研究了在 0.25-50mg/L 范围内不同抗生素浓度下 MFC 的性能。详细研究了 MFC 的发电性能、微生物群落和生物膜特性（形态、电阻和活力）。结果表明，抗生素浓度的增加显著影响了 MFC 的性能和微生物群落。使用改进的非竞争性抑制模型来预测四环素类抗生素对 MFC 的抑制作用。
