Figure 1. Time-course of P. freudenreichii CIRM-BIA1^T metabolic activity over a 40 h-incubation at 30°C followed by a further 9 days at 4°C.

Lactate was added at 64 h (↓) to mimic cheese ripening conditions. A, growth monitored by optical density (650 nm) measurements (black circle), lactate consumption (cross), production of acetate (white triangle) and propionate (black triangle); B, production of pyruvate (white rhombus) and succinate (black rhombus), consumption of aspartate (white triangle) and asparagine (black triangle); C, production of methylbutanoate (sum of 2-methyl- and 3-methylbutanoate acids). ¥: sampling times for microarray experiments.
