How do Shewanella find their way to an insoluble electron acceptor? Being insoluble, it won't release any species for chemotactic receptors to interact with. Li et al examine the possibility that flavins, water soluble electron transfer mediators produced and released by Shewanella, may in their oxidized form also serve the bacteria to sense the proximity of insoluble electron sinks.
