Abstract
In this work have been presented the results of investigations of growth indications, pigment formation, catalase activity and the MDA content in Dunaliella cells, grown in photoreactors being supplied by air mixture with the 100С and 50С temperature (low temperature stress) in control and the treatment with dyes of Methylene blue and Norflurazon herbicide in various concentrations. It was shown that, the treatment of cells with Methylene blue in low temperature stress conditions decreases the cell bioproductivity. In those conditions on the suppression background of Norflurazon bioproductivity, small herbicide concentration 4*10-7М stimulates the culture grows. It has been identified that, the influence of Norflurazon suppresses the carotenoid synthesis and Chlorophyll in low temperature stress conditions. It was determined that, the treatment of algae by the dyes of Methylene blue and Norflurazon herbicide increases intercellular catalase activity in Dunaliella cells. Methylene blue increases MDA level in Dunaliella cells, but Norflurazon suppresses it in low temperature stress conditions.
