Reduction of viable cell number of Xanthomonas campestris pv. campestris (Xcc) after CAC-717 treatment. Xcc suspension (8.22 log₁₀ colony forming units (CFU)/mL) was mixed with an equal quantity of CAC-717 (a) and incubated at 25 °C for the indicated times (0, 0.5, 1, 2, or 5 min). As a control, Xcc suspension mixed with an equal quantity of distilled water was subjected to incubation at 25 °C (b) or 50 °C (c) for the indicated times (0, 0.5, 1, 2, or 5 min). After treatment, the samples were plated on yeast extract–dextrose–CaCO₃ (YDC) medium at 25 °C for 3 days, and the bacterial cell number was determined as colony forming units (CFU)/mL. Data shown as mean ± SEM (standard error of the mean) of triplicates and are representative of two independent experiments; * and ** indicate significant differences (p < 0.05 and p < 0.01, respectively) versus the control (0 min) by non-repeated measured analysis of variance (ANOVA) followed by Bonferroni correction. NS: no significant difference versus control (0 min).
