Figure 1From: Cheese whey-induced high-cell-density production of recombinant proteins in Escherichia coliThe effect of different inducers (IPTG 0.5 mM, lactose, whey and whey permeate) on expression of Adh in E. coli RB791 pQE30 adh . Initial glucose concentration was 1 g l-1. At the onset of induction (at O.D.500 = 0.9), 5 g l-1 glycerol was added to each sample. Adh-production is expressed as units per litre.Back to article page
