Microbial Community Analysis of a Methane-Producing Biocathode in a Bioelectrochemical System
Figure 3
Fluorescence microscopy of the center of the biocathode revealed rod-shaped methanogens that were attached to the graphite felt fibers as single cells ((a) and (b)) or as microcolonies (a). Scanning electron microscopy (SEM) pictures of rod-shaped microorganisms at the center of the biocathode ((c), (d) and (e)). Part of the graphite felt was covered with a dense biofilm (c), while parts were only covered with clusters of microbial cells ((d) and (e)).
