The aim of this module is to provide students with practical experience of up to date bioprocessing techniques and equipment, and further their understanding of the principles of operation of bioreactors and auxiliary on-line measuring equipment, including data acquisition systems. Students will achieve this by performing laboratory experiments incorporating elements of bioreactor operation and bioreaction monitoring techniques. Students will gain experience of various USP and DSP unit operations, and will learn how to interpret the data that they collect and complete a written report.

Learning Outcomes

1. Set up a laboratory scale bioreactor and explain the functioning of all components
2. Carry out a complete sterilization of the bioreactor and auxiliary equipment
3. Explain the functioning of all electrodes/sensors used in the bioreactors and how to calibrate and maintain them
4. Inoculate bioreactor and monitor bioreactor conditions
5. Determine the volumetric oxygen mass transfer coefficient (kLa) for a bioreactor
6. Measure the heat transfer coefficient for heating and cooling in a bioreactor
7. Take samples over the course of the fermentation and measure the biomass concentration
8. Operate an ultrafiltration module and measure NWP
9. Pack a chromatography column and measure efficiency
10. Produce a report in a format suitable for publication in a scientific journal
