Abstract:

In this research was studied the effect of different level of salinity on the catalase ferments activity, proliferation, pigment composition and photosynthetic activity of Dunaliella Salina IPPAS D-24 cells. In the experiments were studied also the activity of catalase ferments of intensely culture green micro-algae in the regime different temperature (50C, 100C, 270C) composition. It is identified that the maximal proliferation temps and photosynthetic activity of Dunaliella Salina is observed in the 1,5M concentration of NaCl. The decrease (1,0 M NaCl and increase 3,0M NaCl) of salinity in the environment causes the fall of cell proliferation. Investigation of catalase activity of green micro-algae cultivated intensively in the nutritious medium of Abdullaev-Semenenko with various NaCl concentrations (1,0M, 1,5M, 3,0M ) showed that the maximum activity of the enzyme is observed during cultivation in 1.5M NaCl concentrated medium. As the temperature of the air mixture inflicted on photoreactors decreases (temperature stress), cell populations' rates of reproduction decrease, at the same time stimulating catalase activity.
