Measurements were taken at 0 h (right after inoculation), 8 h, 25 h, and 34 h of incubation. Mean delta values represent differences of population compared to the control. Different letters in superscript (a–c) indicate differences in the mean values of the different samples within the same hour of incubation. Measurements that have a statistically significant difference to the control are highlighted by asterisk (*). The level of significance was set at p ≤ 0.05.
