Abstract:
Monocellular layers of stationary phase cells of Escherichia coli B/r were exposed to high vacuum of 10(-6) Torr at different temperatures. After simultaneous irradiation with UV of 254 nm or X-rays, the survival was tested as colony forming ability. In vacuum the sensitivity to UV and X-rays was enhanced compared with the controls at atmospheric pressure. Of UV-inactivation in vacuum no photoreactivation was found.
