Shewanella oneidensis
Shewanella is the sole genus included in the Shewanellaceae family of marine bacteria, some species within it were formerly classed as Alteromonas. Shewanella bacteria are a normal component of the surface flora of fish and are implicated in fish spoilage.
Contents
Shewanella oneidensis MR-1 is a widely used laboratory model to study anaerobic respiration of metals and other anaerobic extracellular electron acceptors, and for teaching about microbial electrogenesis and microbial fuel cells.
Shewanella donates electrons to a fuel cell anode
Diet
Shewanella species respire a variety of electrons acceptors in anoxic conditions, many of which are located extracellularly. The mechanism for extracellular electron transfer involves c-type cytochromes that span the inner and outer membranes and "bacterial nanowires".
