Figure 1From: A unique in vivo experimental approach reveals metabolic adaptation of the probiotic Propionibacterium freudenreichii to the colon environmentNumber of induced and repressed genes in the colonic environment, compared to spent medium, classified by metabolic function. In grey and in black: induced and repressed genes, respectively. Differential comparisons between groups were performed gene by gene using a modified t-test. Genes were declared as differentially expressed (DE) with a P value ≤ 0.001 and |fold change| > 2.Back to article page
