ОТВЕТНЫЕ РЕАКЦИИ АНТИОКСИДАНТНОЙ СИСТЕМЫ И ФУНКЦИОНАЛЬНАЯ УСТОЙЧИВОСТЬ К УФ-В ИЗЛУЧЕНИЮ КЛЕТОК DUNALIELLA SALINA IPPAS D-294 МОДИФИЦИРОВАННЫХ 2,6 ДИ-ТРЕТБУТИЛ ФЕНОЛОМ В ОПТИМАЛЬНЫХ УСЛОВИЯХ И ПРИ ВЫСОКОЙ СОЛЕНОСТИ.

In the paper is shown that under the optimal conditions (1,5M NaCl), in the intensively accumulative mode of cultivation, the daily optical density of the cell suspension increases by 3,5-4 times, under conditions of high salinity (3,0M NaCl), by only 3 times. With an increase in the salinity of the mineral medium, the indicators of photosynthetic oxygen release are suppressed by 17%. It was found that the modification of cells with different concentrations (25-500 mkM) of 2,6 di-tret-butyl phenol under conditions of 1,5M NaCl and 3,0M NaCl salinity of the mineral growing medium contributes to a decrease in the content of synthesized pigments, suppression of the POL process, as well as an increase in catalase activity. It was revealed that, under conditions of high salinity of the mineral environment, the modified cells of Dunaliella salina IPPAS D-294 have increased functional resistance to the action of various acute doses of UV-B radiation.
