Shewanella oneidensis is an iron respiring gamma-proteobacterium with unique electrical properties. It appears to have the ability to migrate toward areas of high redox potential by sensing redox gradients of the flavin molecules that it excretes. Dubbed electrochemotaxis, this novel form of taxis is poorly understood. The goal of my research is to identify the mechanism and genetic underpinnings of flavin electrochemotaxis, which may shed light on how some organisms are able to localize to insoluble substrates necessary for their survival.
