Methods of pretreating lignocellulosic biomass with reduced formation of fermentation inhibitors |
| abstract |
Methods of pretreating lignocellulosic biomass in preparation for enzymatic saccharification and fermentation are provided. Also provided are methods of producing ethanol from lignocellulosic biomass via enzymatic saccharification and fermentation that utilize the pretreatment method. In the methods, pretreatment is conducted in two stages. In the first stage, the lignocellulosic biomass is treated in a mildly acidic or near pH-neutral solution to promote delignification and lignin sulfonation, while minimizing the formation of degradation products that inhibit subsequent enzymatic saccharification and/or fermentation. In the second stage, the pH of the solution is decreased in order to promote the depolymerization and dissolution of hemicelluloses in the lignocellulosic biomass. |
