Figure 1. Relative survival of L. plantarum strains subjected to an in vitro GI-tract assay.

Relative viability loss of L. plantarum strains harvested from logarithmic phase (panel A) or stationary phase (panel B) of growth after 60 min (dark grey) gastric juice incubation and subsequent 60 min (light grey) pancreatic juice incubation. The starting population size is set at 0 Log₁₀ CFU ml⁻¹, the data presented are averages of technical triplicates (+ standard deviation). Strains depicted in bold in panel B were present in the bacterial preparation consumed by subjects 1 to 5.
