Microbial Community Analysis of a Methane-Producing Biocathode in a Bioelectrochemical System

Figure 1

Schematic representation of the cathode chamber with the locations of the samples (dark grey squares) used for microbiological analysis. Samples were about 1 × 1 cm2. The high flow zone is where the cathode was in contact with the straight part of the flow channels, while the low flow zone is where the cathode was located in a dead zone. The graphite felt electrode (light grey) was placed between two supportive flow channel plates. The total projected surface area of cathode was 361 cm2, while the effective geometric channel surface area was 290 cm2.
