Fig. 4From: Adaptation of Propionibacterium freudenreichii to long-term survival under gradual nutritional shortageConcentrations of free amino acids in the medium (mM) during growth and stationary phases. In dark blue at the time of inoculation, in red at 1d post-inoculation, in green at 3d post-inoculation, in purple at 9d post-inoculation, in light blue at 11d post-inoculation. Significant consumptions discussed in the text (serine, asparagine, glycine, alanine) correspond to the difference in concentration at 1d and 3d post-inoculation (t-test, P value adjusted <0.05)Back to article page
