Title: Current Production and Metal Oxide Reduction by Shewanella Oneidensis MR-1 Wild Type and Mutants.

Abstract

Shewanella oneidensis MR-1 is a Gram negative facultative anaerobe capable of utilizing a broad range of electron acceptors, including several solid substrates. S. oneidensis MR-1 can reduce Mn(IV) and Fe(III) oxides, and can produce current in microbial fuel cells. The mechanisms that are employed by S. oneidensis MR-1 to execute these processes have not yet been fully elucidated. Several different S. oneidensis MR-1 deletion mutants were generated and tested for current production and metal-oxide reduction. The results showed that a few key cytochromes play a role in all of the processes but that their degree of participation in each process is very different. Overall, these data suggest a very complex picture of electron transfer to solid and soluble substrates by S. oneidensis MR-1.
