Table showing mean and statistical analysis values for calculation of log kill for BIs. The mean number of bacteria remaining, standard deviation (SD), standard error of the mean (SEM), coefficient of variation (%CV) and 95% confidence interval are calculated as described in Table S1. Log kill was calculated as Log10 (value x) – Log10 (value y); where x is the value at 0 min (after gassing) and y is the value for any specified time point. The log kill values are based on the total mean BI cfu remaining values. Given hat there was no inactivation of BIs between no exposure and 0 min (after gassing), the starting value is taken as the 0 min value (3.22E+05).
