The present invention relates to a method using sulfite pretreatment to overcome recalcitrance of lignocellulose (SPORL). More specifically, it relates to a sulfite-based chemical process for pretreating biomass in solutions to reduce access barriers of enzymes to the lignocellulose, resulting in efficient conversion through enzymatic saccharification.

Research targets cells to reduce lignin, boost fermentable sugar
Researchers at the Joint BioEnergy Institute are exploring new ways to meet the challenge of recalcitrant cellulosic feedstocks and lower the cost of biomass-based biofuels. The group recently published two papers detailing their work to genetically modify xylan and lignin, resulting in improved conversion characteristics in the model plants used in the research.
