From: Initial development and structure of biofilms on microbial fuel cell anodes
Graphs showing the relationship between % viability of closed circuit (A) and open circuit (B) MFC experiments. Biofilm viability increases closer to the anode when the electrode is active. Adjacent CLSM images (20 ×) are both 72 hour side-views of S. oneidensis biofilms from batch experiment detected using the Live/Dead (baclight) stain. Circle: G. sulfurreducens, Square: P. aeruginosa, Upright triangle: S. oneidensis, Upsidedown triangle: E. faecium and Diamond: C. acetobutylicum
