Overview

Novel strategy enhances recombinant protein production in E. coli, suggesting corn steep liquor as an economical medium.

Key Points

  • Investigate the use of corn steep liquor as a culture medium for producing a GST/Snakin-Z fusion peptide in Escherichia coli.
  • Cultivated E. coli strains BL21, DH5α, and Mach1 in Luria-Bertani and corn steep liquor media.
  • Used low incubation temperatures of 25°C and 37°C with and without IPTG induction.
  • Measured optical density (OD600) and wet biomass to assess growth and production of recombinant peptide.
  • Mach1 showed the highest OD600 values of 1.25 and 1.26 in CSL at 25 °C and 37 °C respectively.
  • BL21 reached wet biomass of 6.33 mg/ml and 6.67 mg/ml in CSL at the same temperatures.
  • IPTG induction increased peptide production in some strains, but not all, and was not significantly affecting at higher temperatures.
