Cold Chain Handling for Microbial & Bacterial Fermentation

Microbial, bacterial and mammalian cell fermentation are processes performed during media and drug development for the production of biologics, especially vaccines. Smaller biologics, such as antibody-drug conjugates and small antibody and peptide fragements are mostly manufactured with microbial and bacterial fermentation. Product quality, process control and safety are key criteria in current good manufacturing practices (cGMP) of upstream bioprocessing. Ultimately, the fermentation aspires to support cultivation of microorganism to achieve high-cell density and high productivity in final culture generation.

Microbial and Bacterial Fermentation Manufacturing

Microbial and bacterial fermentation open up new possibilities in advanced therapies. They are building blocks for gene-editing, conjugations and DNA plasmids which are all crucial element in improved vaccine production.

The challenges to be overcome in fermentation development are to promote growth rate, cell viability and productivity. Associated fermentation process steps include sizing the ferment, activating polysaccharides and supplementing media to help stabilize the drug substance before the final conjugation can be completed. For improved fermentation production, manufacturing sites must be equipped with scalable, cost-effective and robust process solutions for large volumes up to hundreds of liters per batch.

Quick Freezing & Thawing of Large Volumes for Fermentation in Pharma

Ensure High Product Potency during your Cold Chain

Whether continuous or fed-batch manufacturing, using microbial or bacterial fermentation processes, large volumes of process intermediates may be transported in bulk for completion and final conjugation and further clinical manufacturing in the area of gene-editing, plasmid DNA, antibody-drug conjugates and vaccine manufacturing.
