Time course of metabolic activity of seven P. freudenreichii strains over a 40-h incubation at 30°C followed by a further 80 h at 4°C. Growth (OD650nm, optical density at 650 nm) (A), concentrations of methylbutanoate (sum of 2-methylbutanoate and 3-methylbutanoate) (B), propionate (C), and acetate (D). Error bars show the standard deviations of the results of triplicate independent experiments. The inset in panel A shows the growth curves at 4°C and 30°C. Values are means for the 7 strains: CIRM-BIA1T (×), CIRM-BIA9 (△), CIRM-BIA118 (□), CIRM-BIA122 (▲), CIRM-BIA123 (○), CIRM-BIA472 (●), CIRM-BIA482 (■).
