The relatively low sensitivity is an important reason for restricting the microbial fuel cell(MFC)sensors'application in low concentration biodegradable organic matter(BOM)*** startup parameters,including substrate concentration,anode area and external resistance,were regulated to enhance the sensitivity of MFC *** results demonstrated that both the substrate concentration and anode area were positively correlated with the sensitivity of MFC sensors,and an external resistance of 210Ωwas found to be optimal in terms of sensitivity of MFC *** MFC sensors had lower detection limit(1 mg/L)and higher sensitivity(Slope value of the linear regression curve was 1.02),which effectively overcome the limitation of low concentration BOM *** essential reason is that optimized MFC sensors had higher coulombic efficiency,which was beneficial to improve the sensitivity of MFC *** main impact of the substrate concentration and anode area was to regulate the proportion between electrogens and nonelectrogens,biomass and living cells of the anode *** external resistance mainly affected the morphology structure and the proportion of living cells of the *** study demonstrated an effective way to improve the sensitivity of MFC sensors for low concentration BOM detection.

关键词： Microbial fuel cell sensor High sensitivity Biodegradable organic matter Substrate concentration Anode area external resistance
