Abstract

Shewanella oneidensis was found to be electrochemically active, and to metabolize lactate in a fuel cell-type electrochemical cell in the absence of electron acceptors with concomitant current generation. These properties were not observed in a cell-surface cytochrome mutant. Similar electrochemical activities were measured in various bacteria. Based on these findings, similar electrochemical cells were used to enrich electrochemically active microbes with different nutritional characteristics and used in a series of optimization experiments to overcome rate-limiting factors. Based on the results, reactors with different configurations were designed including a membrane-less MFC. A maximum power density of 2.9 w/sq m was achieved with a BOD removal rate of 41.7 kg/cu m-day with the sludge generation ratio of 0.1 g dryweight/g BOD removed. Diverse bacterial populations were found in the enriched fuel cell depending on the fuel used through molecular ecological methods including DGGE, 16S rDNA sequencing, and FISH. This is an abstract of a paper presented at the 230th ACS National Meeting (Washington, DC 8/28/2005-9/1/2005).
