Summary. Maximum colony counts of unheated and heated spores of Bacillus stearothermophilus were obtained after incubation at 50‐65°C and 45‐50°C, respectively. the composition of the plating medium was found to have a marked effect upon recovery of unheated and heated spores. the effects of diluent and incubation time on recovery have also been investigated.
