Photobacterium marinum is a gram-negative, oxidase and catalase positive, motile bacteria of the genus Photobacterium.[1] Photobacterium marinum are commonly found in marine environment.[1] S.I. Paul et al. (2021)[1] isolated, characterized and identified Photobacterium marinum from marine sponges of the Saint Martin's Island Area of the Bay of Bengal, Bangladesh.
