Fig. 4From: Surface display of p75, a Lactobacillus rhamnosus GG derived protein, on Bacillus subtilis spores and its antibacterial activity against Listeria monocytogenesAntibacterial effect of CotG-p75 against L. monocytogenes. Cells were treated with different concentrations of CotG-p75 in PBS at 37 °C. The control groups were treated with no spores (closed square) or wild-type spores (closed triangle). The number of viable cells was measured at intervals of 1 h during the 6 h incubation. All tests were performed in triplicate, and the data are presented as mean ± standard deviation. Statistical analysis was performed by an unpaired two-tailed t-testBack to article page
