Figure 3From: Electrochemical selection and characterization of a high current-generating Shewanella oneidensis mutant with altered cell-surface morphology and biofilm-related gene expression Protein contents of the anode biofilms, supernatant, and cathode biofilms in single-chamber MFCs, showing the distribution of wild-type (WT) and EC-2 cells. Error bars represent standard deviations of means that were calculated from at least four assays.Back to article page
