Photo-electrochemical communication between cyanobacteria (Leptolyngbia sp.) and osmium redox polymer modified electrodes
Abstract
Photosynthetic microbial fuel cells (PMFCs) are an emerging technology
for renewable solar energy conversion. Major efforts have been made to
explore the electrogenic activity of cyanobacteria, mostly using
practically unsustainable reagents. Here we report on photocurrent
generation (approximate to 8.64 mu A cm(-2)) from cyanobacteria
immobilized on electrodes modified with an efficient electron mediator,
an Os2+/(3+) redox polymer. Upon addition of ferricyanide to the
electrolyte, cyanobacteriia generate the maximum current density of
approximate to 48.2 mu A cm(-2).... Show more
