Abstract BACKGROUND: The release of antibiotics into aquatic environments has made the treatment of wastewater
containing antibiotics a world-wide public health problem. The ability of microbial fuel cells (MFCs) to harvest
electricity from organic waste and renewable biomass is attracting increased interest in wastewater treatment.
In this paper we investigated the bioelectrochemical response of an electroactive mixed-culture biofilm in MFC to
different tobramycin concentrations.
RESULTS: The electroactive biofilms showed a high degree of robustness against tobramycin at the level of μg/L.
The current generation responses of the biofilms were affected by the presence of tobramycin. The inhibition ratio
of the MFC increased exponentially with the tobramycin concentrations in the range of 0.1-1.9 g/L. The bacterial
communities of the biofilms vary with the concentrations of tobramycin, the equilibrium of which is critical for the
stability of electroactive biofilms based-MFC.
CONCLUSIONS: Experimental results demonstrate that the electroactive biofilm-based MFC is robust against
antibiotics at the level of μg/L, but sensitive to changes in antibiotic concentration at the level of g/L. These results
could provide significant information about the effects of antibiotics on the performance MFC as a waste-treatment
technology.
