Cultures of E. coli strains constitutively expressing the GFP in semi-defined medium supplemented with 10 g L⁻¹ glucose and 4 g L⁻¹ yeast extract. The left panel shows scattered light intensities, and the right panel shows GFP fluorescence intensities. A, B Cultures of strains WG, WGE, WEP and WHI; C, D cultures of strains WGB, WGME, WGMX, and WGMP; E, F cultures of W3110, WGM, WGX and WGMB; G, H cultures of strain WHIC. Culture conditions: 48 well FlowerPlates®, V_L = 800 µL, n = 1500 rpm, d₀ = 3 mm. Note that the scales are not identical. Shaded bands indicate the standard deviation between triplicate experiments
