Our group appears in the newsletter of the company Agarose Bead Technologies. Our experience in the use of agarose resins to immobilize enzymes is summarized. The complete testimonial can be downloaded here
Course on Analytical and Semipreparative Liquid Chromatography HPLC. Teaching included seminars and practical sessions. The number of participants was 22, coming from different cities in Spain. The practical sessions included the separation of sweeteners in a soft drink by ionic chromatography, the analysis of a mixture of polyphenols by reverse phase HPLC, the separation of the components of a synthetic biodiesel mixture, and the scaling-up of an analytical separation of carbohydrates.
We have shown that the beta-fructofuranosidase from X. dendrorhous fructosylates several carbohydrates that contain glucose. In particular, the enzyme produces selectively neo-erlose from maltose. In this way novel hetero-fructooligosaccharides with food and pharmaceutical applications can be obtained.

Hope, peace and love for you this Christmas!
Professor Stephen G. Withers gave a conference in our institute on “New access to complex glycoconjugates through engineering and evolution of glycosyltransferases and glycosynthases". Prof. Withers, Khorana Professor of Biological Chemistry at the University of British Columbia (Vancouver, Canada), has made substantial contributions to the understanding of mechanisms of glycosidic enzymes, using such information to the development of potential new therapeutics for Influenza, Diabetes and Gaucher disease.
Master of Biotechnology at UAM. Teaching included seminars and practical sessions on the biocatalysis field.
Barbara Rodriguez-Colinas has defended her Thesis entitled "Enzymatic synthesis, characterization and prebiotic properties of oligosaccharides employed in infant milk formulas", supervised by Antonio Ballesteros and Francisco J. Plou. She obtained the maximum qualification (Sobresaliente cum laude). Congratulations to her!
