Fig. 6: Differential gene expression of L. monocytogenes after GI stress in food matrices compared to growth in food for seven days.

Changes in the gene expression of L. monocytogenes (p adj < 0.05, log2FoldChange ≥ |2|) of virulence and stress resistance genes in sausage, fish, and cheese after passage through the artificial GI model compared to growth in the three food matrices for seven days.
