Shewanella putrefaciens CN-32

Shewanella_putrefaciens
Names Shewanella putrefaciens CN-32
Accession numbers NC_009438
Background 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. S. putrefaciens CN32 was originally isolated from anaerobic sandstone at a depth of 250 m in the Morrison formation of northwestern New Mexico. It, and related species of metal-reducing Shewanella, effectively reduce polyvalent metals and radionuclides including solid phase Fe and Mn oxides and contaminants including U(VI), Tc(VII), and Cr(VI). The solubility of these contaminants is greatly diminished at lower oxidation states and hence microbial reduction has been proposed as a means for stabilizing contaminants in situ (adapted from http://genome.jgi-psf.org/shepu/shepu.home.html).
