Fermentation
Fermentation — A large-scale biotechnological process using microorganisms to produce recombinant peptides and proteins in bioreactor systems.
What Is Fermentation?
Fermentation is the growth of microorganisms (bacteria, yeast) in bioreactors to produce recombinant peptides and proteins. E. coli fermentation is the primary production method for peptide hormones too long for efficient chemical synthesis (> 50 residues), including insulin, growth hormone, and parathyroid hormone.
Process
- Fed-batch: Nutrients added continuously during growth. Standard for E. coli peptide production
- Inclusion bodies: Many peptides overexpressed in E. coli form insoluble aggregates requiring denaturation and refolding
- Downstream: Cell lysis, centrifugation, refolding, chromatographic purification
