WebThey show an exponential decay in the numbers of the test bacterial culture. After one or two logs worth of bacterial killing, the experiment is usually terminated because the experimenter has enough points to establish a good curve fit and so is able to calculate a statistically significant decimal reduction value (D-value). WebLog reduction is a measure of how thoroughly a decontamination process reduces the concentration of a contaminant. It is defined as the common logarithm of the ratio of …
