Light-Dependent Electrogenic Activity of Cyanobacteria
Figure 3
Light dependent oscillations in anode potential.
Anode potential in a Nostoc containing half MFC (black line) was found to oscillate relative to an Ag/AgCl reference electrode as a function of illumination. An identical anode devoid of biofilm (gray line) was unresponsive to illumination. 12 h dark-phases are indicated by black bars along x-axis.
