Biofilm biomass (OD_{590 nm}) of P. fluorescens pf5 in mono- and dual-species with L. monocytogenes strains on a polystyrene (PS) surface at 12 °C for 168 h. The results are expressed as an average of five replicates and the bars represent the standard deviations. The asterisk (*) indicates statistically significant difference between the mono- and dual-species samples for the same incubation time (* p < 0.05). (a) 48 h, (b) 72 h, (c) 96 h, and (d) 168 h.
