Figure 4. Crude Wa F17.12-KT extract activity assays.

Figure 4

The susceptible strains CaATCC 24433 (A) and WaUM3 (B and C) were incubated for 12 h at 26°C at pH 4.5 (A and B) and 8 (C) with WaKT crude extracts (19X) from WaF17.12, WaATCC 96603 (WaKT-producing strain) or WaUM3 (WaKT non-producing strain). Crude WaKT activity was evaluated using the trypan blue test reporting the number of vital cells/ml of the two target strains and the values are reported as mean±SEM (n = 6). Asterisks refers to the statistical significance of the differences, according to the One Way ANOVA and Bonferroni’s Multiple Comparation Tests.
