Abstract
The shungite effect on the culture of green chlorococcal microalga Scenedesmus quadricauda (Turp). Breb was studied based on the amount of 100 g / l potassium dichromate at a concentration of 3 mg/l. In the presence of shungite, the culture growth stimulation was observed, and in the presence of potassium dichromate the growth inhibition occurred compared to the control. It is shown that the combined action of potassium dichromate and shungite on the Scenedesmus quadricauda population eliminates toxic effect of potassium dichromate. The most rapid growth of the culture occurred when only shungite was added to the culture medium, while the photosynthesis efficiency, number of cells and proportion of living cells increased in the presence of shungite. Apparently, shungite in the culture medium acts, on one hand, as sorbent, and on the other alters the redox state of the medium. The mechanism of action of shungite is nonspecific and can be used as a universal remedy for water purification from various pollutants.
