Full Description

This powerpoint presentation begins by providing information on the biodegradation of the following: MC-LR; multiple microcystins; single compounds; cocktail; and, nodularin - Rescobie. The isolation of bacteria is presented, including:enrichment;classical microbiology;12 Pseudomonads and 6 Bacilli; and,carbon utilization - Biolog MT2 MicroPlate. Presentation conclusions indicate the following:microcystin degradation is more common thanpreviously thought;pre-exposure to microcystins is not essentialfor efficient degradation;greater diversity of degradation intermediatessuggests greater microbial diversity;natural populations appear to be more effectivethan individual isolates; and,Biolog MT plates can be a useful screen and havesupported the isolation and characterization of3 novel microcystin degrading bacteria. Includes table, figures.
