Shewanella putrefaciens is a acquatic Gramnegative bacterium that was originally isolated from the sediments of Lake Oneida It has been isolated from marine environments. S. putrefaciens is an important model organism for bioremediation because of its diverse respiratory capabilities conferred by multicompetents systems and besides that, also use branched electron system. S. putrefaciens is a facultatively aerobe, however the diverse respiratoy capacity such as anaerobic conditions offer an ability and a advantage to reduce iron and other oxidized metals metabolically by terminal electron acceptors chain (in contrast to obligate aerobes which must use oxygen for this purpose), these metals includes manganese and iron. The bacterium have the capacity to thrive at low temperatures and the Genome analysis predicts energy-generating pathways for many fermentative end products (e.g., acetate, fumarate, pyruvate), that analisis also shows the presence for metabolic pathways for sugars and glycerol. In this way S. putrefaciens have several biotechnological uses, so it can be widely applied in waste containing high concentrations of metals such as waste frying oils which bind to metals varied depending on the tool used.
