Effects of jaburetox on bacteria. Bacterial multiplication was evaluated by absorbance at 620 nm at time zero, and 4 and 24 h after incubation in the presence of different concentrations of JBTX. a Bacillus cereus; b Escherichia coli; c Pseudomonas aeruginosa; d Staphylococcus aureus. Growth in the presence of buffer (Tris HCl 10 mM pH 7.0) or H₂O₂ was considered as negative and positive control, respectively. Each graph represents three independent experiments in triplicates for each condition. Results are mean ± SD. Asterisks (*) indicate statistical differences (p values ≤ 0.05, Tukey test).
