WWSC Wood Biopolymer Characterization Webinars

Webinars starting December 3, 2021

Welcome to a webinar series where you meet international experts on wood biopolymer characterization. Take the chance to learn more about the characterization, ask questions and discuss in this webinar series, held online via Zoom meetings. 

The focus will be on learning and let the participants gain more insight into the characterization of wood biopolymers and the techniques that is used.

Register to receive a link to the Zoom-webinars. The webinars are open for all to attend.

Program

Part 1: Mass spectrometry for wood biopolymer analysis

Webinar 1:
December 3, 14.00 – 15.30 CET

Introduction to wood biopolymers: Challenges for molecular characterization

Francisco Vilaplana

Analysis of chemically modified polysaccharides by mass spectrometry

Prof. Petra Mischnick, TU Braunschweig, Germany

Polysaccharides, especially cellulose and starch, are chemically modified in various ways in order to change their natural properties and open a wide field of application, for instance in construction, food, and pharma. Beside the type of derivative formed, the average degree of substitution (DS) and the distribution of the substituents in a polyfunctional polymer have a significant impact on the resulting physicochemical properties. Beside proper sample preparation, mass spectrometry is a key tool in the  analysis of the complex substitution pattern of such materials.

Petra Mischnick was professor at the Institute of Food Chemistry of Technische Universität Braunschweig until 2020 and, from 2008-2012, at KTH Stockholm, FPT.

Her main research interests are focused on polysaccharides and polysaccharide derivatives, especially on the comprehensive analysis of structure and substituent patterns

Webinar 2:
December 10, 14.00 – 15.00 CET

Insights into fine molecular structure of hemicelluloses and lignin through chromatography and mass spectrometry
 

Assoc. Prof. Mirjam Kabel, Wageningen University and Research, The Netherlands

This presentation will highlight chromatographic and mass spectrometric methodologies to (enzymatically) fingerprint hemicelluloses to obtain insights into their molecular structure. In addition, attention will be paid to analytical challenges related to quantification and identification of lignin.
 

Dr Kabel worked on fungal, enzymatic and thermochemical lignocellulose conversion for >20 years and has a strong expertise in plant biomass analytics and biochemistry. Relevant projects relate(d) to 2nd generation bioethanol, feed conversion, and optimal substrate production for commercial white button mushroom. 

Her group is well equipped with sophisticated analytics combining chromatographic, mass spectrometric and NMR technologies.
