Description

Shewanella are facultatively anaerobic, Gram-negative bacteria, motile by polar flagella, rod-like, and generally associated with aquatic or marine environments. . They are capable of using a variety of compounds as electron acceptors, including oxygen, iron, manganese, uranium, nitrate, nitrite, fumarate, to name but a few. This ability makes Shewanella important for bioremediation of contaminated metals and radioactive wastes. The genus Shewanella comprises 36 recognized and hundreds of uncharacterized cultivable species. It uses oxygen as the terminal electron acceptor during aerobic respiration; however during anaerobic conditions, S.oneidensis undertakes respiration by reducing alternative terminal electron acceptors such as oxidized metals, fumarate, nitrate etc. Shewanella species can directly reduce both uranium and chromium from the dissolved liquid state. Such abilities could facilitate the removal of dilute metal pollutants in both contained-storage and natural sites. Additionally S.oneidensis can immobilize toxic metals through the formation of insoluble metal sulfides. Finally it has been proposed for bioremediation of anoxic polluted sites. S.oneidensis might prove useful for direct bioremediation of both metal and organic pollutants under anaerobic conditions.
