Shewanella haliotis is a species of rod shaped, gram negative, mo-tile bacilli that grow aerobically or anaerobically and produce hydrogen sulfide. Members of Shewanella were found in a variety of places, such as activated sludge, seawater, sediment, invertebrates, and fish, but are usually found in marine environments in warm climates. Shewanella can live on land, deep inside Earth, or underwater. As their habitat changes Shewanella changes with it, finding new ways to breath. This bacterium plays an important role is co-metabolic bioremediation of halogenated organic pollutant. Shewanella strains are found to possess the ability to degrade a variety of azodye, triphenylinethane, and other anthraquinone dyes. Considering their potential marine
