WebSpores are more resistant to sterilization since they are in a state of hibernation. As an example of a biological F value calculation, if the D value is known to be two minutes and a 12-log reduction in that spore indicator organism is required for sterilization, the minimum F value required is 24 minutes. Web6 log reduction = 99.9999% reduction As the series demonstrates, if a log reduction is a whole integer, then its numerical value equals the number of nines in the percent …
