Abstract

Lack of fundamental understanding of cellulase interactions with different plant cell wall components during cellulose saccharification hinders progress toward achieving an economic production of biofuels from renewable plant biomass. Here, chemical force microscopy (CFM) was utilized to quantify the interactions between two surfaces that model either hydrophilic or hydrophobic functional groups of cellulases and a set of lignocellulosic substrates prepared through Kraft, sulfite, or organosolv pulping with defined chemical composition. The measured forces were then decoupled into specific and nonspecific components using the Poisson statistical approach. Heterogeneities in the distributions of forces as a function of the pretreatment method were mapped. Our results showed that hydrophobic domains and chemical moieties involved in hydrogen bonding and polar interactions were homogeneously distributed on all substrates but with distribution densities that varied with the type of the pretreatment method used to prepare substrates. In addition, we showed that increasing surface lignin coverage increased the heterogeneity of the substrates. When forces were decoupled, our results indicated that xylan reduced the strength of hydroge...Continue Reading
