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.
Biochemical characteristics of Photobacterium marinum
P. marinum has an optimum growth temperature of 30 °C.[2] Cells contain poly-β-hydroxybutyrate granules that are visible with transmission electron microscopy.[2] Similar to other members of the genus, P. marinum is oxidase positive and catalase positive.
