Figure 4From: Cultivation of E. coli carrying a plasmid-based Measles vaccine construct (4.2 kbp pcDNA3F) employing medium optimisation and pH-temperature induction techniquesDry cell concentration and cell growth rate profiles during fed-batch fermentation of E. coli DH5α-pcDNA3F. Glycerol feeding was initiated at 10 h post culture and temperature upshift (37°C to 45°C) was performed at 20 h post inoculation. Rhombus: dry cell concentration; triangle: cell growth rate.Back to article page
