Fig. 3From: A comprehensive study of the promoting effect of manganese on white rot fungal treatment for enzymatic hydrolysis of woody and grass lignocellulose2D HSQC NMR spectra of raw, Pc-treated and PcM-treated poplar. a, b and c aromatic (δC/δH 100–140/6.0–8.0) region, d, e and f aliphatic (δC/δH 50–90/2.5–6.0) region. Unassigned, amino acid and carbonhydrate residues are shown in gray. See Additional files for spectra of other fungal-treated lignocelluosic feedstocks (Additional file 1: Figure S4 and S5). The annotated substructures of correlated peaks are shown in Additional file 1: Figure S6Back to article page
