Fully automated production of potential Malaria vaccines with Pichia pastoris in integrated processing

摘要

Here, we have studied the setup of an integrated bioprocess for the production of artificial Malaria vaccine candidates with Pichia pastoris. Production of pharma-ceutically relevant proteins such as vaccines has high demands regarding protein processing in the bioreactor and for subsequent purification. To implement this challenging protein expression process, a highly instrumented bioreactor was configured for repeated fed batch cultivations and supplemented with an at-line monitoring of the targetprotein production via HPLC. The integration of a fast in situ purification of the sensitive products using an expanded bed adsorption for a sequential integrated bioprocess allows cyclic product separation. Thus, a fully automated production of artificial malaria vaccines was achieved.
