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

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.
