Figure 4: Antimicrobial activity of lyophilized of Pediococcus pentosaceus SB83 against Listeria monocytogenes 2092 4b in simulated vaginal fluid at pH = 6.5 during storage at room temperature (black lines) and at 4°C (grey lines). ((a) and (d)) Counts of viable cells of Listeria monocytogenes 2092 4b; ((b) and (e)) counts of viable cells of Pediococcus pentosaceus SB83; ((c) and (f)) pH of simulated vaginal fluid overtime are represented. These parameters were evaluated at storage time of 0 (), 1 (■), 3 (▲), 6 (×), 9 (җ), and 12 ( ) months. All points are means ± standard deviations.
