Fig. 6From: Four ways of implementing robustness quantification in strain characterisationRobustness over time for intracellular parameters. a R(t) denotes how stable a function of systems (S) is over time for each condition (C). R(t) can be used to compare the same perturbation between different strains (systems) or within the same strain to assess how different media affect function stability. b R(t) for eight intracellular parameters (left to right, top to bottom): ATP level, intracellular ATP, pyruvate metabolism, ethanol respiration, glycolytic flux, ribosome abundance, oxidative stress, and unfolded protein response. Red dots identify the mean R(t) across all media and replicates for each strainBack to article page
