Adaptation of Microorganisms to Radiation

  • Alan M. Shefner


Adaptations of microorganisms to particular environmental stresses have been frequently observed and may be initiated by a variety of causative factors. If the stress imparts a selective advantage to variants in the culture, or if it induces an increased frequency of mutations to forms with a selective advantage, the original strain may vanish with time and be replaced by a strain better adapted to the changed environmental conditions. It is an example of such a stress and response that I intend to consider.
