Figure 2. Maximum likelihood phylogenetic tree (JTT + I + G) of the Propionibacterium freudenreichii strains used in this study.

The 12 strains shown in boxes were used in the proteomics study and the eight strains with a grey background were also used in the transcriptomics study. IL-10 levels were normalised within each donor using B. longum (BB536) induced levels as a reference and averaged over four donors.
