Abstract
Factors have been studied which are responsible for the resistance of cells of several strains of Chlorella to physical and chemical stresses; measurements have been made of the effects of UV and x irradiation, heat treatment, detergents, cadmium salts, and insecticides. Cells which were resistant to the effects of physical factors were also resistant to chemical intoxication. A positive correlation was found between the resistance of cells to the described factors and the level of endogenous thiols in the cells, as well as the free radical content. This in turn is due to an increased number of reaction centers in the electron-transport chain.
