Toxicity prevents the bioenergy content of certain industrial effluents from being recovered. In operation of microbial fuel cell (MFC), microorganisms can be inhibited with high levels of sulfides. This study applied a pure culture, an autotrophic denitrifier, Pseudomonas sp. C27, to start up a two-chambered MFC using sulfide as the sole electron donor. The experimental results revealed that the MFC can successfully convert sulfide to elementary sulfur with electricity generation at a maximum power density of 29.3 mW m -2. With no use of external organic carbon sources, the present device introduces a route for treating sulfide laden wastewaters with electricity harvest. © 2012, Hydrogen Energy Publications, LLC.
