Table 2 pDNA production parameters

From: Heterogeneous oxygen availability affects the titer and topology but not the fidelity of plasmid DNA produced by Escherichia coli

  1. P pDNA titer at the end of cultivation, Y P/X average of the individual pDNA specific yield values during exponential growth, q P pDNA specific production rate, Q P pDNA global productivity, SCF average of the individual supercoiled pDNA fraction values during exponential growth. The data represent the average ± standard deviation of 3 independent experiments
