FIG 1.

Robustness of L. lactis strains upon exposure to heat stress expressed as the difference between log CFU/ml after heat stress (Nt) and control (N0). For genotype-phenotype matching, the strains were divided into groups of robust (striped bars), intermediate (black bars), and sensitive (gray bars) strains. Strain names indicated with a triangle represent strains that were selected for the spray drying analysis (see Fig. 4). The data represent averages of two biological replicates. Error bars indicate standard deviations.
