From: Cheese whey-induced high-cell-density production of recombinant proteins in Escherichia coli

Production of Adh in E. coli RB791 pQE30 adh with different combinations of the carbon sources glycerol and whey permeate. An initial glucose concentration of 1.0 g l-1 was used in all cultures. Induction was performed at O.D.500 = 0.4. A) growth measured as OD500; B) Volumetric activity of recombinant Adh.
