In our experiments with Chlorella sorokiniana, having in mind that 100 mg x [L.sup.-1] selenate strongly inhibited cell growth and provoked severe cell deformation and death, as proven by ultrastructure microscopy, maximal (100%) growth inhibition was set for 100 mg x [L.sup.-1], and the obtained [EC.sub.50] value from the log-logistic model curve was 45 mg x [L.sup.-1] (Figure 1(c)).
