Fig. 4

A Colony forming units (CFUs) of S. thermophilus and L. delbrueckii over 18 h of growth when cultured alone, in pairwise combinations, or in the original starter cultures (RMK). The ribbons illustrate the interquartile range and the lines the modeled growth curves. B Acidification curves of the same samples. The ribbons illustrate the min and max pH of the different samples. C Principal component analysis of the metabolic profiles after 24 h of growth at 37 °C. Different treatments are highlighted in colors and with the surrounding eclipse.
