By: A. Pereira n, I. Hoeger n, A. Ferrer  n, J. Rencoret *, J. Rio *, K. Kruus *, J. Rahikainen *, M. Kellock *, A. Gutierrez *, O. Rojas n

MeSH headings : Adsorption; Cellulose 1,4-beta-Cellobiosidase / chemistry; Eucalyptus / chemistry; Hydrogen Bonding; Hydrophobic and Hydrophilic Interactions; Lignin / chemistry; Lignin / isolation & purification; Microscopy, Atomic Force; Picea / chemistry; Plant Stems / chemistry; Protein Binding; Quartz Crystal Microbalance Techniques; Static Electricity; Surface Plasmon Resonance; Surface Properties; Trichoderma / enzymology; Triticum / chemistry; Wood / chemistry
TL;DR: A strong correlation between enzyme binding and the syringyl/guaiacyl (S/G) ratio was found for the lignins, which presented a similar hydroxyl group content (31P NMR), which furthers the understanding of lignin-cellulase interactions relevant to biomass that has been subjected to no or little pretreatment.
