Abstract
Real-time and simultaneous measurements of
bacterial catalyst loading and electron transfer have
been accomplished via a microfabricated transparent
electrode within the setup of a micro- microbial fuel
cell (μMFC [mu MFC]). By characterizing the electron transfer
on a per cell basis, we aim to generate a methodology
for species-to-species comparison and formulate a
baseline for electrode optimizations. This is critical
and fundamental knowledge to be explored within
the scope of MFCs as power devices with direct
implications to molecular cell biology. Preliminary
results are presented showing that, using Geobacter
sulfurreducens, a signal to noise ratio (SNR) of 11
can be achieved upon inoculation and single cells can
be non-invasively and accurately identified using
intrinsic fluorescence.
