Advanced Carbohydrate Technologies

Course content

This course will provide a comprehensive understanding of plant carbohydrates and will use an integrated series of lectures and practical/theoritical exercises to cover fundamental carbohydrate biology and the associated technology. This is followed by presentation of more applied themes by academic and industrial researches. The key lectures will be provided by members the three departments involved, but an important feature of the course will be the involvement of invited external speakers. Students will have opportunities to get hands-on practical experience with state–of-the-art techniques for glycan analysis including carbohydrate microarrays.

Carbohydrates have a large impact on plant development and thereby on cereal based foods or food ingredients that constitutes the major part of the human diet. Carbohydrates are bioengineered to make biofuel and bioenergy more efficient. Further carbohydrates are functionalised in plants and with enzyme processing to generate new functions, health-associated ones, and intelligent and advanced biomaterials.

In the course the theory will be presented, followed by excercises in the technologies described. The course will deal with polysaccharides as they occur in plants, especially important food crops and will cover biosynthesis, diversity, evolution and structure. The theory will be backed up by presentation of the analytical techniques for polysaccharide analysis with a particular emphasis on relating structure to function and the effects of enzymatic and chemical modifications. Also included will be lectures with focus on the applications of plant polysaccharides. This will ex. include plant fibres and health, advanced functional food ingredients, nutraceuticals and therapeutics, novel bio-materials and the production of plant polysaccharides within a bio-refinery context.

Key topics covered:  e.g. functional food ingredients, nutraceuticals, excipients (medical applications), biocomposites, industrial production of fibres from plants, monoclonal antibody production; biosynthesis of plant carbohydrate, biofuel enzyme discovery, rational energy crop design, starch, pectin, plant cell wall, spectroscopic analysis.

The newest examples of techniques will be presented e.g. carbohydrate microarrays, high-throughput antibody screening; hydrocolloid rheology (structure function relationships); high-throughput enzyme screening; immuno-fluoresence microscopy;  bioinformatics relating to the carbohydrate enzyme database (CAZY), viscometric measurements, molecular modeling.
