| Outline of Final Research Achievements |
In this study, we investigated molecular mechanisms underlying interactions between Shewanella oneidensis MR-1 and electrodes in bioelectrochemical systems. The observation of biofilm formation processes using a confocal laser scanning microscope and electrochemical flow cells revealed that MR-1 forms structurally different biofilms on graphite electrodes depending on the electrode potential. We also found that the electrode potential affects the gene expression and metabolic profiles of MR-1, and elucidated the molecular mechanism underlying the electrode potential sensing of this strain.
