ABSTRACT

It has been found that the activity of one of the antioxidant enzymes, catalase of Ceramium rubrum (Huds.) Ag. and Enteromorpha intestinalis (L.) Link, can be used as bioassay in evaluating the ecological state of marine waters. The level of catalase activity corresponding to the normal functioning of algae was determined. It has been shown that the threshold of sensitivity to nitrate in catalase activity of algae accounts for 2 mmol/L; the threshold of sensitivity of catalase activity to nitrite is one order of magnitude less.
