Correlation between luminescence and GFP fluorescence of JB10 strain. (A) Correlation between bioluminescence L and GFP fluorescence F of the JB10 strain, as observed in a bulk (well-plate) experiment. Data were collected at OD = 0.10 in the presence of exogenous C8HSL and 3OC6HSL spanning a range of concentrations from zero to ~ 1000 nM. (B) Same data plotted as L1/2 vs F, showing the approximate power law of Eqn. (1). (C) The HSL-independent intercept F 0 in Eqn. (1) grows in proportion to optical density during early growth.
