Growth rates (% increase in surface area per day) of strains 1–24 between days 5 and 7 after inoculation. Pre-exposure data from the EMB exposure experiments (black bars), and data collected in the baseline experiments (white and grey bars) are combined. Diamonds represent the weighted average of all data points for each strain, ranging between 629 and 9608 (median 3911.5) data points per strain. *As shown in Table 1, strains 22 and 24 are the same strain as strain 4, and strain 23 is the same as strain 15, although they were included as individual strains in the blinded panel. Error bars represent the standard deviation of the growth rate of individual microcolonies.
