title: [A means of refining the sterilization criterion].
abstract: The process efficiency parameter used in estimation of thermal sterilization of nutrient media known as a sterilization criterion is replaced by a new one. A methodical approach to and the results of experimental determination of corrections for the sterilization criterion pattern connected with the operation factors are presented. The following parameters for measuring the criterion were elucidated: contamination of nutrient media, retention time and kinetic characteristics of test-microbe death. Sterilization conditions were calculated with the routine procedure and the new method. Comparison of the results showed that the retention time calculated with the account of the corrections was much closer to the experimental values for the time of the test-microbe death.
