Abstract: | A predictive and feedback glucose feed controller, previously developed for nutrient-sufficient growth of Escherichia coli to high cell densities, was used to produce large quantities of a heterologous, cyanobacterial recombinant hexadecameric (L8S8) protein, ribulose 1,5-bisphosphate carboxylase/oxygenase (RubisCO) in E. coli. Culture and plasmid stability conditions were optimized to yield the production of approximately 1 g of soluble, active recombinant RubisCO per liter. Recombinant RubisCO also was produced in lactose-induced high-cell-density fermentation of E. coli K-12. |
