Module Aims
- To review the use of enzymes in key industrial processes, both traditional and recently-evolved, with emphasis on their underlying biotechnological strengths and current limitations. - To outline how biotechnological innovations (especially protein engineering) have resulted in improved products and processes. - To provide an overview of biosensor development. - To emphasize the importance of purification strategies and downstream processing in the large scale production and recovery of commercial biotechnology products.

Learning Outcomes
Students will gain: - An overview of the uses and advantages of enzymes in starch hydrolysis, antibiotic modification and other industrial processes - An overview of structure -determination and bioinformatics techniques used in protein engineering - An understanding of the potential of protein engineering for the tailoring of useful proteins - An appreciation of the scope and potential of enzyme and biosensor technologies in the evolution of current, developing and innovative products/processes- An understanding of the basis of a variety of protein separation methodologies - A grounding in modern chromatographic methods and their applications - The ability to discuss/ predict possible future developments in specific biotechnological industries in the context of developing technologies.
