Media composition effect on the cultures’ growth kinetics. The growth kinetics of the E. coli BL21(DE3) [pET21d(+)-gfpuv], E. coli BL21(DE3) [pET21d(+)-tthHB27IRM] and E. coli BL21(DE3) [pET21d(+)-tp84_28] bacterial cultures in M9 minimal medium and LB media supplemented with different peptones was measured as OD₆₀₀. The cultures were carried out at 37 °C. No gene expression-inducing factors were added during culturing
