Figure 3From: Optimizing cofactor availability for the production of recombinant heme peroxidase in Pichia pastoris Effect of medium supplementation with FeSO 4 and hemin on HRP activity in microscale cultivations. Volumetric HRP activity from minimal medium without supplementation was set to 100%. Bars are average values ± SD from independent triplicate cultivations. Light gray, no FeSO4; dark gray, 1 mM FeSO4.Back to article page
