Abstract:
1. A method for treating a biomass comprising a lignocellulosic material to produce fermentable sugars through saccharification comprising: treating the biomass to produce a biomass with a depolymerized lignin; adding a carbonium-ion scavenger to the biomass before, during, or after said treating step to inhibit repolymerization of the lignin; adding a laccase enzyme and a cellulase enzyme to the biomass with depolymerized lignin subsequently to the addition of the carbonium-ion scavenger; and producing a fermentable sugar from the enzymatic actions of the laccase enzyme and cellulase enzyme in the presence of the carbonium-ion scavenger on the biomass with depolymerized lignin; wherein the carbonium-ion scavenger is 2-naphthol.
