Whole cell wall NMR analysis on original and digested Japanese cedar (softwood), Japanese beech (hardwood), and rice straw (grass) lignocellulose diets fed to C. formosanus termite workers. (a) Differential 2D ¹H–¹³C correlation (HSQC) spectra for digested versus original cell walls. (b) Changes in relative signal abundances determined for major lignin aromatic and polysaccharide anomeric signals appearing in the original and digested cell wall spectra. For signal assignments and structure abbreviations, also see Table S1.
