From: Production of recombinant protein by a novel oxygen-induced system in Escherichia coli

Parameter (units) pAB828 batch, 30% dO2 pAB828 batch, 300% dO2 pAB49 batch, 300% dO2 pAB49 fed-batch, 300% dO2
Amount of GFP in the total soluble protein (%) 5.1 ± 0.31 4.9 ± 0.38 1.5 ± 0.03 3.4 ± 0.11
Specific fluorescence (FU/μg GFP) 13753 ± 880 14464 ± 1065 10831 ± 191 11617 ± 1048
  1. ± refers to the standard deviation between triplicates.
