Optimization of the medium perfusion rate in a packed-bed bioreactor charged with CHO cells

Urs von Stockar

In the present study, the optimal medium perfusion rate to be used for the continuous culture of a recombinant CHO cell line in a packed-bed bioreactor made of Fibra-Cel disk carriers was detd. A first-generation process had originally been designed with a ...

Culture analysis and external interaction models of Mycelial growth

Thomas Liebling

To investigate morphogenesis and in particular circularization mechanisms in young mycelia, we observe cultures of the zygomycete Mucor spinosus and develop discrete models of two-dimensional filamental branching growth. The models are based on the hypothe ...
