The effect of solute concentration on the sensitization of Clostridium perfringens spores to heat by ionizing radiation was investigated. Spores of C. perfringens treated with gamma radiation are more sensitive to subsequent heat treatments than are spores that receive no radiation treatment. When gamma-irradiated spores were heated in the presence of increasing concentrations of glycerol or sucrose, the heat sensitivity induced by irradiation was progressively decreased.
