Figure 4From: Differences in the adsorption of enzymes onto lignins from diverse types of lignocellulosic biomass and the underlying mechanism(A) Expanded side chain ( δ C / δ H 50 to 90/2.5 to 5.5) and (B) aromatic ( δ C / δ H 100 to 150/5.5 to 8.5) regions in the HSQC spectra of lignins. AL, aspen lignin; CL, corn stover lignin; HSQC, heteronuclear single quantum coherence; KL, kenaf lignin; PL, pine lignin.Back to article page
