Table 1 Average maximum growth rates (batch) and dilution rates (chemostat) of the different strains.

From: Effect of iclR and arcA knockouts on biomass formation and metabolic fluxes in Escherichia coli K12 and its implications on understanding the metabolism of Escherichia coliBL21 (DE3)

  Batch Chemostat  
Strain μ max (h-1) D influent (h-1) D effluent (h-1)
Wild type 0.66 ± 0.02 0.099 ± 0.001 0.100 ± 0.001
ΔarcA 0.60 ± 0.01 0.118 ± 0.001 0.120 ± 0.001
ΔiclR 0.61 ± 0.02 0.085 ± 0.001 0.090 ± 0.001
ΔarcAΔiclR 0.44 ± 0.03 0.090 ± 0.001 0.093 ± 0.001
  1. Under chemostat conditions, the apparent growth rate equals the dilution rate of the influent. Differences between D influent and D effluent are due to addition of base and acid for pH correction and sampling.
