Photobacterium is a genus of gram-negative, oxidase positive and catalase positive bacteria in the family Vibrionaceae.[1] Members of the genus are bioluminescent, that is they have the ability to emit light.
Many species, including Photobacterium leiognathi and Photobacterium phosphoreum, Photobacterium ganghwense, Photobacterium marinum live in symbiosis with marine organisms.[1] S.I. Paul et al. (2021)[1] isolated and identified multiple strains of Photobacterium from marine sponges of the Saint Martin's Island Area of the Bay of Bengal, Bangladesh.
Species such as Photobacterium profundum are adapted for optimal growth in the deep cold seas making it both a psychrophile (an organism capable of growth and reproduction in cold temperatures) and a piezophile (an organism which thrives at high pressures).
