It was shown from probability consideration that the life-span distribution of spore clumps could be represented as shown in Fig. 1. The following two conclusions were obtained from the results : the life-span distribution of spore clumps was similar to the normal distribution, the calculation of which was based on the negative exponential distribution for the life-span of single spores; the heat resistance of spore clumps, if represented by the average life-span, increased approximately proportionally to the logarithm of the number of single spores incorporated into the clumps as shown in Fig. 2.Assuming that individual spores incorporated into spore clumps contribute to the probability of nusuccessful sterilization, curves of (1-P^*) (curves 2 and 3) correcting for the value of (1-P) (the probability of unsuccessful sterilization and the value can be determined experimentally from the plate counting method) was plotted against time, θ as shown in Figs. 3,4,5. It is clear that the corrected curves can much better account for the deviation of the date points from curve 1 (for (1-P)).
