Movie S1. Glucose–cellobiose diauxie. Time-lapse experiment of Lactococcus lactis M1gfp grown in a medium supplemented with both glucose (0.1%) and cellobiose (1%) (G-C medium). After glucose is depleted from the medium, two subpopulations emerge. The GFP expression is driven from Pcel and indicates cellobiose utilization.
