The survival of mid-exponential and the early-stationary E. coli K12 and L. acidophilus were investigated when spray drying and outlet air temperatures of 60, 70, 80, 90 and 100°C. The results showed that the early-stationary cell of both cultures had a greater heat resistance than the mid-log cell in every drying temperature. The best survival rate was found when spray drying at temperature lower 80°C and it is showed that L. acidophilus is stronger than E. coli K12 (irrespective of the growth phase).
