Lecture Topic

"Using donut-shaped oligosaccharides to remove hazardous substances"


Prof. KIDA Toshiyuki


Professor, Division of Applied Chemistry, Graduate School of Engineering, Osaka University

Lecture Overview

Cyclodextrin (CD) is a donut-shaped oligosaccharide obtained when enzymes interact with starch, and due to its shape, it contains a subnanometer-sized vacancy, or hole, that can hold molecules. This ability to hold molecules, called "inclusion," is widely used in food, cosmetics, and pharmaceuticals. CD is also gathering attention in the environmental field as a material that can remove harmful substances in water. However, molecular inclusion by CD has mostly been performed in water, as this inclusion is thought to be difficult to perform in nonpolar solvents and oils, and had yet to be achieved. Recently, we have successfully developed a CD derivative that can effectively perform this "inclusion removal" of harmful materials in oil. At this lecture, I'll explain inclusion of this newly-discovered CD derivative in nonpolar solvents, as well as the removal of polychlorinated biphenyls (PCB) in contaminated oil using this CD derivative.
