Figure 8.

Grouped bar chart displays four panels (A–D) showing mean values with error bars at three time points (24, 48, and 72 hours) for different sample groups indicated by color-coded legends. Letters above bars indicate statistical significance within each time point. Panel (A) compares 1N3, 2N5, and 1N3+2N5; (B) compares 1N3, 3N1, and 1N3+3N1; (C) compares 2N5, 3N1, and 2N5+3N1; (D) compares 1N3, 2N5, 3N1, and 1N3+2N5+3N1. Horizontal axes show time points and vertical axes show numerical values ranging from zero to 0.9.

Effect of co-cultivation of P. alliivorans (1N3), P. asturiensis (2N5) and P. viridiflava (3N1) on biofilm production. (A) 1N3 + 3N1; (B) 1N3 + 2N5; (C) 3N1 + 2N5; (D) 1N3 + 2N5 + 3N1. Mean absorbance values at 600 nm measured after 24, 48, and 72 h of incubation are reported. Error bars represent the standard error. Statistical differences at each time point were assessed using ANOVA followed by Tukey’s post-hoc test, or by Kruskal–Wallis followed by Dunn’s post-hoc test when assumptions of normality and homogeneity of variances were not met (p < 0.05).
