Coefficient of variance vs. mean fluorescence intensity for the triple reporter strains E. coli G7_BL21(DE3) (grey squares) and E. coli G5_T7E2 (black circles) grown with minimal medium in batch cultures in stirred-tank bioreactors (T = 37 °C, pH = 6.8, initial glucose concentration 20 g L⁻¹). Values for single cell growth related to rrnB-EmGFP expression (a), general stress response of single cells related to rpoS-mStrawberry expression (b) and oxygen limitation of single cells related to nar-TagRFP657 expression (c) are depicted as average of triplicate measurements
