Reasons of chlorella strain's resistance to physical and chemical factors of environment

Abstract

Under environmental pollution it is necessary to study the reasons of an organism's resistance as well as the specificity of it. Some chlorella strains were under the influence of uv- and x-irradiation, heat treatment, cadmium salts, insecticide, and detergent. It was shown that cells which were resistant to physical factors were resistant to chemical intoxication, as well. The positive correlation between resistance of strains and the described influences and the levels of endogenic thiols was found. The second reason for higher resistance is an increase of free radicals' concentration. It is linked with increasing P/sub 700/ quantity of electron-transport chains that make possible higher levels of photosynthetic reactions of resistant cells.
