Based on D values obtained over the temperature range of 121.1 C (250 F) to 126.7 C (260 F), Bacillus stearothermophilus vegetative cells sporulated in the presence of milk were more resistant to heat inactivation than spores grown on nutrient agar fortified with MnSo4. Spores grown in the presence of milk and heat-treated at 121.1 and 126.7 C had D values of 4.7 and 0.8 min, respectively. Spores grown on fortified nutrient agar and beat-treated at 121.1 and 126.7 C had D values of 3. 7 and 0.55 min, respectively. No difference in heat resistance was observed between spores derived from vegetative cells grown in milk or nutrient broth when tested at 121.1 C.
