The response of gamma -irradiated bacteria to nutritional substances differed considerably with species (or strains); the increase of survival by the addition of nutritional substances was greater in bacteria capable of growing without any growth factor (e.g., Escherichia coli and Serratia marcescens) as compared with organisms which require a variety of organic substances for growth (e.g., Proteus morganii and, particulary, spores of Bacilius subtilis). On the basis of these findings, the relationship between the processes involved in the "recovery" of bacterial cells inactivated by gamma -radiation and the biosynthetic systems contained in the cells of each species (or strain) is discussed. Evidence was obtained with Escherichia coli and Serratia marcescens which indicated that most of the irradiated cells showing induced nutritional requirements were not stable auxotrophic mutants.
