Figure 9From: Bioreactor mixing efficiency modulates the activity of a prpoS::GFP reporter gene in E. colicell viability at the level of the two subpopulations (GFP+ and GFP-). The green channel (FL1) depicts the GFP expression level and the red channel (FL3) depicts the degree of PI absorption by the cells with a compromised membrane. Sample taken after 16 h (A), 25 h (B), 30 h (C) of culture in a partitioned reactor (Qrecirc = 18 L/h).Back to article page
