Environmental factors affecting the production of peptide toxins in floating scums of the cyanobacterium Microcystis aeruginosa in a hypertrophic African reservoir

The toxin content of buoyant scums of Microcystis aeruginosa was quantitatively determined and related to various environmental factors, using samples collected during a 2.5 year period at the hypertrophic Hartbeespoort reservoir, South Africa. Six cyclic heptapeptide toxins were separated using rev...
