Fig. 1From: Metabolic adjustment upon repetitive substrate perturbations using dynamic 13C-tracing in yeastProfile of the experimental feeding and sampling regime. After a chemostat phase (reference steady-state), a block-wise feed is applied at the same average substrate supply and dilution rate. Intracellular concentrations are measured by sampling two cycles, then the feed is switched to labeled substrate and the enrichment is monitored for three consecutive cyclesBack to article page
