Fixed-bed reactors have gained growing attention for the cultivation of mammalian cells. They allow for a low shear stress cultivation of adherent and non-adherent cells due to the immobilization of cells within macroporous carriers. Their potential has been demonstrated for many cell culture purposes. Some of the recent developments are presented in this review, including improved antibody pro...

BACKGROUND Yeast expression systems with altered N-glycosylation are now available to produce glycoproteins with homogenous, defined N-glycans. However, data on the behaviour of these strains in high cell density cultivation are scarce. RESULTS Here, we report on cultivations under controlled specific growth rate of a GlycoSwitch-Man5 Pichia pastoris strain producing Granulocyte-Macrophage Co...
