Mechanochemical deconstruction of lignocellulosic cell ...

In this work, the deconstruction mechanism of corn stover cell wall polymers during ball milling was evaluated. The characterization showed that ball milling not only brought about the dissociation of the cross-linked cellulose-hemicellulose-lignin complex but also led to the depolymerization of the cell-wall polymers especially the carbohydrates.

Application of intermittent ball milling to enzymatic ...

Hydrolysis of lignocellulosic biomass is important for isolation of glucose in a biorefinery. In this research, intermittent ball milling was applied to facilitate and enhance enzymatic hydrolysis of dilute acid-pretreated lignocellulosic biomass, with the highest glucose yield of 66.5% at a low enzyme dose (10 FPU g−1 glucan) over 24h. In comparison, the yield for the typical liquid …
