Attaching to Surfaces and Passing around Electrons: the Things Microbes do

Presented by:Professor Kenneth Nealson Wrigley Professor of Geobiology,
Earth Sciences Abstract: The microbe Shewanella oneidensis MR-1, isolated from anaerobic metal-rich sediments, is representative of a group generally referred to as dissimilatory metal-ion reducing microbes -- those bacteria that use oxidized metals as electron acceptors. When presented with insoluble oxidants, MR-1 attaches to the metal surface, forms a primitive biofilm, and proceeds to grow at the expense of metal ion reduction. Properties of Shewanella, its role in metal reduction, and the relationship of these properties to extracellular electron transfer will be discussed including recent results obtained using MR-1 for current production in biofuel cells.Refreshments will be served at 2:30p.m. All first-year MASC students are required to attend.
