This powerpoint presentation begins by providing a brief overview of the issue of cyanobacteria in
Canada and Australia. The study objective was the oxidation of Anabaena circinalis cells and
Paralytic Shellfish Poison (PSP) by
chlorine in order to:
determine the extent of cell lysis and
toxin release in natural water;
assess the rates of oxidation of total
PSP by free chlorine; and,
estimate apparent rate constants for
PSP oxidation in ultrapure and natural
waters. Experimental materials and methods included the following:
oxidation of Anabaena circinalis cells and PSP release and degradation by chlorine; and,
oxidation of dissolved PSP by chlorine. Study conclusions indicate the following: low chlorine doses resulted in the quick
release and subsequent oxidation of PSP
from a toxic strain of A. circinalis;
efficient toxin treatment may occur without
complete cell lysis; and,
the chlorination of PSP in cell-free extract
and cellular suspensions of A. circinalis
followed the same trend. Includes tables, figures.
