Topic of thesis: Mixing and oxygen transfer processes in bioreactors

Starting date: January 2013 

Background: M.Sc. in Biotechnology, Technical University of Denmark

Supervisors: Krist V. Gernaey, Brian Madsen, Stuart M. Stocks

Mixing of bioreactors is important, especially for aerobic fermentations where the maximum production rate in growth associated production systems is usually limited by the mixing and the mass transfer capabilities in the system. An open question to be investigated in this project is whether the current reactor design and mixing equipment design are sufficient to obtain the highest productivity. It is indeed known that there is spatial heterogeneity in a large scale bioreactor, but it is not known in detail how this will influence productivity of the reactor at industrial scale.

A unique feature of the project is that data will be collected on industrial scale fermentations. The project should indeed provide basic knowledge about the limiting factors in the oxygen transfer in an industrially relevant fermentation matrix. Experimental data collection on industrial scale fermentations will be possible in collaboration with Novozymes A/S and Novo Nordisk A/S as part of the BIOPRO biotechnology cluster.
