Efficiency of the regeneration procedure in removing the living and dead bacterial biomass from the biodeteriorated cathode. New – MFC operating for 2 weeks; biofouled – MFC operating for 3 months; regenerated – MFC operating for 1 month following regeneration. The percentage values are indicating the contribution of subpopulations in the total bacterial population. Samples were taken from the 2nd MFC in the cascade.
