A Z value is defined as the number of (°C) degrees Celsius required to change a D value by one factor of 10. For instance, increasing the sterilization temperature by 10 °C will result in a log reduction of the D value if the population’s Z value is 10 °C. It takes at least three D value/temperature pairs to calculate a Z value.
WebD-value (microbiology) In microbiology, in the context of a sterilization procedure, the D-value or decimal reduction time (or decimal reduction dose) is the time (or dose of an antimicrobial drug) required, at a given condition (e.g. temperature) or set of conditions, to achieve a log reduction, that is, to kill 90% (or 1 log) of relevant ...
