Shewanella sp. ANA-3

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. Shewanella strain ANA-3 was originally isolated from a wooden pier within a brackish estuarine environment at Woods Hole, USA, and is characterized by a unique As(V) respiratory metabolism and a remarkable salinity tolerance range. Moreover, ANA-3 grows faster and at higher temperatures (37 C) than many other Shewanella species. However, it does not grow with DMSO as terminal electron acceptor, as most Shewanella species do (adapted from http://genome.jgi-psf.org/she_a/she_a.home.html). (HAMAP: SHESA)
