Investigation of E. coli, Cladophora, and Microcystin in Saginaw, Grand Traverse, and Little Traverse Bays

Dr. Richard Rediske has been awarded a $59,86  grant by the Michigan   Department of Environmental Quality (MDEQ) to assess two water   pathogens: the bacterium E. coli and the cynobacterial (blue-green   algal) toxin microcystin found in Cladophora mats in the nearshore   waters of Grand Traverse Bay, Little Traverse Bay, and Saginaw Bay.    Cladophora is a filamentous green alga that has become a nuisance in   some areas of the Great Lakes, forming thick mats that wash on shore   and foul beaches. Beginning in June 2  8, samples will be collected   at eight beach locations in each of the three bay sites. These   samples will be analyzed for E. coli and microcystins, which both   pose human health risks when present in high concentrations. This   grant also examines the role of Cladophora mats in the sequestration   of E. coli and microcystins in important recreational areas in   Michigan. Dr. Rediske will be collaborating with the Great Lakes   Water Studies Institute at Northwestern Michigan College in Traverse   City and setting up a laboratory to analyze the E. coli samples.    The Water Studies Institute also will coordinate outreach activities   with support from The Watershed Center Grand Traverse Bay and the   Tip of the Mitt Watershed Council.    (cladophora); (E. coli); (Escherichia coli); (human health);   (microcystin); (microcystis); (algal bloom); (algal blooms);   (HAB's); (HABs); (HAB); (harmful algal blooms); (harmful algal   bloom); (cyanobacteria); (blue-green algae); (Saginaw); (Michigan);   (Traverse Bay); (microcystins)
