Optimized bioprocess enhances rGLP-1 yield in E. coli, suggesting improved treatment affordability.

To improve the yield and productivity of recombinant glucagon-like peptide-1 (rGLP-1) analogues in E. coli.
Designed expression constructs for monomeric and concatemeric GLP-1 fused to GST.
Conducted batch fermentations at varying growth rates to inform a fed-batch strategy.
Optimized fermentation process to maximize specific yield and productivity.
Purified rGLP-1 using affinity chromatography and corroborated with Western blot and mass spectrometry.
Achieved specific yield of 116.7 mg/g and dry cell weight of 88.9 g/L.
Volumetric yield reached 10.3 g/L with specific productivity of 0.4 g/L/h.
The optimized process can potentially reduce production costs by 20–30%, improving accessibility of GLP-1 therapies.
