Description The purpose of this module is to provide students with the skills and understanding necessary for handling and quantitation of micro-organisms in a laboratory environment. To this end, you will work through Standard Operating Procedures commonly used in food and water microbiology and use procedures for surfaces to quantify microbial contamination. This is a continuously assessed laboratory module and attendance is compulsory and will be monitered. | |||||||||||||||||||||||||||||||||||||
Learning Outcomes 1. Analyse food and water samples for microbes and use these findings to determine the quality of food and water samples. 2. Culture microbes in batch and continuous culture, graphically analyse the results and use these to calculate microbial growth parameters. 3. Carry out a sequential 'multistep' protein purification scheme including ion-exchange and gel filtration chromatography and calculate yield and purification. 4. Carry out HPLC analysis to determine the concentration of an analyte and its purity. 5. Write up reports, to be viewed by an experimental scientist and by the general public, detailing their experimental findings and the conclusions that may be drawn from them. | |||||||||||||||||||||||||||||||||||||
