Recombinant gene expression in Escherichia coli cultivation using lactose as inducer.

Abstract

The use of lactose as inducer of foreign gene expression under control of the lac UV5 promoter was investigated in recombinant Escherichia coli. Chicken muscle troponin C (TnC) gene was transcripted by T7 RNA polymerase and expressed in bioreactor cultivations after a feed-forward controlled fed-batch growth phase. Cell concentrations of 22 g l-1 dry cell… (More)
