Fig 2. Flow cytometry fluorescence density-plot analysis (Q₁ dead, Q₂ injured and Q₃ live cell population) of L. rhamnosus CRL 1505 grown in MCM broth and harvested at stationary phase of growth.

Untreated cells (maintained at 37°C for 5 min) in potassium phosphate buffer (a) and after heat shock in different media: potassium phosphate buffer (b), MCM broth (c), MCM3 (d), MCM4 (e) and MCM5 (f). Values are the average of at least two experiments.
