Structural Characterization of Lignin

CD BioSciences has developed a variety of biophysical methods to help clients characterize lignin structure and composition, providing theoretical guidance for the construction and optimization of degradation processes, as well as providing important information for the efficient use of lignin. Our professional scientific services will accelerate the progress of your project in the field of lignin structure research.


Structural Characterization of Lignin

Lignin is a unique and abundant natural biopolymer that accounts for 15-30% of the dry weight of biomass. Previous studies have shown that lignin is a non-crystalline and highly branched phenolic polymer. Lignin imparts structural strength and biological activity to plants and plays an important role in pathogen defense, water and nutrient transport. Its physicochemical properties play a crucial role in the production of the material. Therefore, elucidating the structural characteristics of lignin is a prerequisite for its efficient use.

To date, researchers have mainly degraded lignin by destructive methods in order to analyze the structure of lignin. In this approach, its structural features are likely to be altered as a result of the degradation process. In addition, lignin-carbohydrate complexes (LCCs) make it more difficult to isolate lignin from lignocellulosic biomass (LCBM) and analyze its structure. It is therefore essential to develop new techniques for mapping accurate structures of whole lignin. The development of techniques and instrumentation in the biophysical field offers the possibility of studying the structure of lignin as a whole.

Our Services

  • Characterization and elimination of undesirable protein residues.
    We provide characterization and elimination of undesirable protein residues, which interfere with the characterization and quantification of lignin. This step leads to a clearer picture of the H-unit structure in lignin, offering researchers the possibility to elucidate the structure of lignin more clearly.
  • Characterization of the structure of lignin and its degradation products.
    We offer several NMR techniques such as 1H, 13C and 2D NMR, as well as a range of spectroscopic methods. Using these techniques, we help our customers to obtain quantitative information on lignin degradation products and to resolve the complex structure of lignin.
  • Structural characterization of LCC.
    We offer a variety of techniques to identify the structure and number of lignin-carbohydrate bonds involved in LCC to help our customers study the structural signatures and degradation behavior of LCC in lignocellulosic biomass.
  • Detection of Lignin-Polysaccharide Interactions.
    We offer a variety of high-precision and high-resolution techniques to analyze lignin-polysaccharide interactions to help our customers improve their understanding of the molecular level organization of lignocellulosic biomass.
