FIGURE 5

Heat map distribution of bacterial phylotypes classified to the lowest level possible (class, order, family or genus) for A- and P- reactors: anode of A-reactors (A), suspension of A-reactors (B), anode of P-reactors (C) and suspension of P-reactors (D). A, anode and S, suspension. Bacterial phyla representing less than 1% of the relative abundance are classified as others. The taxa level shown on the left-hand side of the panel represents the lowest classification level possible (order, family or genus), while the taxa level on the right-hand side represents class. Scale on top left-side of each panel is relative abundance (%). Each cell represents the average of duplicate reactors. Each column represents a specific sampling period (AL/PL: days 0, 10, 30, 50, and 70; AH/PH: days 0, 15/20, 35, and 70). Day 0 represents the MFC anode that was transferred to individual MECs after three cycles of reproducible voltage.
