Lignin aromatic units and polysaccharides in original and digested diet samples of N. hirtum. Aromatic (a) and polysaccharide anomeric (b) sub-regions 2D HSQC NMR spectra of pine wood and Shorea artificial diet lignocellulose samples before (“original”) and after (“digested”) digestion by N. hirtum larvae. Figures show normalized signal intensity values of major lignin aromatic and polysaccharide anomeric signals expressed as percentages of the sum of the listed signals (see Materials and methods) (c) and ratios of non-oxidized and oxidized syringyl (½S2/6 and ½Sʹ2/6) and guaiacyl (G2 and Gʹ2) lignin aromatic signals (d). Data labeled × 5 indicate that the reported values are multiplied by 5 for visualization purposes. Peak assignments are listed in Table 2
