The ability to produce and to transport exo-electrons by microbes either to
external acceptors or to electrodes are reported in our study. All investigated
microorganisms (exception of Lactobacillus plantarum) exhibited strong iron-
reducing capabilities in the absence of mediator meaning production and secretion
of exo-electrons to the growth medium. Lactobacillus plantarum, Saccharomyces
cerevisiae and Escherichia coli need an electron shuttle molecule to reduce Fe3+
ion. Significant correlation was observed between growth and iron-reducing
capacity, as well as between initial cell counts and iron-reducing capacity. Changes
of bio-current generated in MFC and iron-reduction were experimentally
monitored, and a mathematical model was established by regression analysis.
Based on these results, a novel and rapid screening method was developed for the
selection of microorganisms for potential application in MFC. The method is based
on the measurement of absorbance of bacterial and yeast cultures at 460 nm,
providing a robust and high sample throughput approach.
