Figure Lengend Snippet: Log reduction results. a) Comparison of D-values (dose per log reduction) for all tested microorganisms on the stopper surface. The vegetative species were tested in the wet state, while the spores were tested in the dry state. b) Selected log-reduction graphs showing log reduction versus dose. Each raw data point is an average of three measurements, and the error bar represents one standard deviation. The data was fitted to single exponential functions. The horizontal dashed line represents the required reduction level (either 3 or 6 log), and the required dose at that level is indicated by the intersection with the vertical dashed line. The axis is zoomed in from 0 to 250 mJ/cm2, and in some cases, there are unseen datapoints (following the exponential trend) outside of this window.
