Robust enzymatic saccharification of a Douglas-fir forest harvest residue by SPORL

Creator:

Leu, Shao-Yuan, Zhu, J. Y., Gleisner, Roland, Sessions, John, and Marrs, Gevan

Abstract:

Forest harvest residues can be a cost-effective feedstock for a biorefinery, but the high lignin content of forest residues is a major barrier for enzymatic sugar production. Sulfite pretreatment to overcome strong recalcitrance of lignocelluloses (SPORL) was applied to a Douglas-fir (Pseudotsuga menziesii (Mirb) Franco var. menziesii) forest residue in...

Using sulfite chemistry for robust bioconversion of Douglas-fir forest residue to bioethanol at high titer and lignosulfonate: A pilot-scale evaluation

Zhu, J. Y., Chandra, M. Subhosh, Gu, Feng, Gleisner, Roland, Reiner, Rick, Sessions, John, Marrs, Gevan, Gao, Johnway, and Anderson, Dwight

Abstract:

This study demonstrated at the pilot-scale (50 kg) use of Douglas-fir forest harvest residue, an underutilized forest biomass, for the production of high titer and high yield bioethanol using sulfite chemistry without solid–liquor separation and detoxification. Sulfite Pretreatment to Overcome the Recalcitrance of Lignocelluloses (SPORL) was directly applied to the...
