X-irradiation at 2-10 kr stimulates cell division, increases the biomass and the rate of photosynthesis within the first day of development of the culture. On the 5th day these processes are inhibited as compared with the control. Doses exceeding 10 kr inhibit the development of purple sulfur bacteria, but doses up to 30 kr do not cause any regular change in the ratio:[image]Irradiation of these bacteria with X-rays at doses of 0.5 to 30 kr does not favor bacterial development in the absence of light.
