Structural characterization of the lignins from sugarcane bagasse and straw

The structure of the lignins of sugarcane bagasse and straw was investigated. The lignins were characterized both in situ and in isolated preparations (Milled-Wood Lignin, MWL, and Cellulolytic Lignin, CEL) by Py-GC/MS and 2D-NMR. It was concluded that they are p-hydroxyphenyl-guaiacyl-syringyl lign...
