RÉSUMÉ

Paper presents results of investigations of the effect of sodium humate and potassium humate on concentration of chlorophyll a and carotenoids and intensity of lipid peroxidation in several species of Cyanoprokaryota and Chlorophyta. Response of the considered algae to the impact of alkaline metals humates was shown to depend on the species specificity and on active ingredient concentrations. In most cases humates of potassium and sodium in concentrations of 5 and 10 mg/dm3 stimulated functioning of the investigated species of green microalgae, whereas Cyanoprokaryota species were suppressed.
