S

hewanella putrefaciens. S. putrefaciens is a member of the Proteobacteria (Gamma class). It is a facultative anaerobe, and uses can use either iron or manganese as the terminal electron acceptor in electron transport (most organisms use oxygen). This organism derives its name due to the fact that it produces trimethylamines, which means it takes on a rotten fish smell. Yummy. Growing this organism will reveal that it has a pinkish color upon isolation. Another interesting tidbit is that this organism can also generate electricity.

People have also been unfortunate enough to find themselves infected with S. putrefaciens, though electrocution is not something they need to worry about.
