The relative abundance of monolignols, namely p-hydroxyphenyl (H), guaiacyl (G), and syringyl (S) units (a), and the corresponding monolignols ratio (b), based on Py-GC–MS results of the lignin-rich residues (LRRs) from corn stover (CS), Miscanthus × giganteus stalks (MS), and wheat straw (WS). Data points represent average and standard deviation from two replicates. Different letters (A, B, C, …) indicate significant statistical difference based on ANOVA (P ≤ 0.05)
