Several blooms of cyanobacteria naturally occurring in freshwater reservoirs have been associated to numerous fatalities and cases of livestock and human poisoning. Microcystins (Mcs) are the most frequently found cyclic heptapeptide toxins in the cyanobacterial extracts. In previous work, Radiocyst...
