Figure 2From: Bioreactor mixing efficiency modulates the activity of a prpoS::GFP reporter gene in E. colidissolved oxygen profiles obtained for the different reactor configurations. From top to bottom: well-mixed reactor exponential feed ; well-mixed reactor ON/OFF DO feed control ; partitioned reactor Qrecirc = 18 L/h ON/OFF DO feed control ; partitioned reactor Qrecirc = 36 L/h ON/OFF DO feed control.Back to article page
