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.
