Monster Seminar Jam - Cyanobacterial Toxins in Freshwater Environments: Identifying and Characterizing the Potential Risks (and Some Possible Benefits)
Dr. John Berry, Chemistry and Biochemisty, Florida International University
Cyanobacteria (blue-green) algae produce a myriad of toxic and otherwise biologically active secondary metabolites. In freshwater habitats, these toxins can pose serious threats to human and environmental health. The research to be discussed includes identification, purification and characterization of novel toxins from cyanobacteria, as well as toxicological characterization of previously described toxins, and development of analytical methods for detection and monitoring of these compounds. In particular, each aspect of this research has been greatly facilitated by the use of the zebrafish (Danio rerio) embryo, as an aquatic animal model, and specific applications of this model system to investigate cyanobacterial toxins in freshwater systems, including the Great Lakes and Florida Everglades, will be discussed.
