The genus Photobacterium was first coined by Martin Beijerinck, in 1889, and originally referred to all bacteria capable of light production. Species belonging to Photobacterium are gram negative, rod shaped, chemoorganotrophic, facultative aerobes. They have been associated with seawater surfaces, marine sediments, intestinal organs of marine animals, and saline lake water.
