[The effect of ultraviolet irradiation on the protozoan Tetrahymena pyriformis].
A number of trials was conducted to test the effect of ultraviolet radiation on the protozoan Tetrahymena pyriformis, strain W. The material was cultivated in a culture medium and in a deficient experimental medium, the radiation flux being 90 to 5400 J/m2 in the logarithmic and stationary stages of population growth. As found, the culture medium has a protective effect against ultraviolet radiation, owing to an increased peptone content. The cells in the stationary stage of growth are more resistant to ultraviolet radiation than cells in the logarithmic stage of growth. The studied intensities of radiation did not damage the nutrients contained in the medium.
