Description
In this module the student will undertake an in-depth investigation into oxygen transfer in a bioreactor. Each student will be supplied with a detailed dataset on dissolved oxygen data, as well as cell counts, for a bench scale culture of the yeast Kluyveromyces. The challenge will be to quantify oxygen uptake rates and mass transfer rates while relating these phenomena to cell counts. Students will be expected to be able to draw on what they have learned in BE215 and apply it to the current challenge. On completion of the data analysis the student will write a coherent report detailing their overall approach and in a logical sequence.

Learning Outcomes
1. Analyze experimental data in a critical and creative manner
2. Devise methods for evaluating model parameters by fitting the model to experimental data
3. Use the dynamic simulation package, Berkeley Madonna, to interpret experimental data
4. Produce a coherent laboratory report detailing the outcomes of the research in a logical sequence.
5. Produce high quality graphs of experimental data
