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.[1]

Diet

Shewanella can supply themselves with energy by drawing electrons directly from an external source, using external structures called "nanocables" that can also be used to supply electrons to an external object.[2]

Popular culture

Shewanella has become an icon for teaching about microbial electrogenesis and microbial fuel cells.

Shewanella appeared in a comic book as "Shewy, the Electric Bacterium" in educational kits that are available for students and hobbyists.[3]
