Bactericidal activity of alpha-bromocinnamaldehyde against persisters in Escherichia coli
Fig 1
Hierarchical cluster analysis of the bactericidal effects of CA and its derivatives on E. coli cells in exponential growth phase.
Cell survival percentage after treatment was calculated based on the colony counts on the LB agar plates. Resulting tree figure was obtained using Cluster 3.0 software and Java Treeview. The cluster color bar was shown as [log (cell survival percentage ×100)-2]. If the given amount of drug failed to completely inhibit the bacterial growth, the corresponding values in the bar would be positive in red color; If the given amount of drug showed the bactericidal effects, the corresponding values in the bar would be negative in green color.
