Title
Enhancement of coulombic efficiency and salt tolerance in microbial fuel cells by graphite/alginate granules immobilization of Shewanella oneidensis MR-1
Abstract

•A new immobilization method for electrogenic microorganism was developed.•The conductive granules significantly decreased the internal resistance of MFC.•Higher coulombic efficiency and salt tolerance were achieved with this new method.

Coulombic efficiency and stability of electricity output are crucial for practical applications of microbial fuel cells (MFCs). In this study, a cell immobilization method for electrogenic microorganism in MFCs using graphite/alginate granules is developed. The MFC with immobilized cell granules delivered a much more stable electricity output than that with suspension cells, and resulted in a ∼0.8 to 1.7 times improvement on coulombic efficiency compared to the suspension mode. Impressively, with the conductive graphite/alginate/cells granules, the internal resistance of the MFC decreased dramatically. Moreover, the cell immobilized MFC showed a much higher tolerance to the shock of high salt concentration than the MFC with suspension cells. The results substantiated that immobilization of electrogenic microorganism for MFCs could be achieved by the method developed here, and it is promising for practical application in energy harvesting from wastewater by MFCs.
