A combined effect of temperature, pH and NaCl concentration on thermal inactivation of Bacillus stearothermophilus ATCC 10149 spores was analysed.
After pasteurisation at 80 C for 10 min, the suspension of bacterial spores were sterilised at the temperature
from 110 to 121 C in a medium at different pH values (3–7) and various NaCl concentrations (0–6%)
