SPORL Patent: Ethanol Produced as By-product, or from Waste, or from Cellulosic Material Substrate, or Substrate that Contains Cellulosic Material

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.

JBEI team develops ionic-liquid-tolerant bacterial cocktail for cost-effective biomass pretreatment for cellulosic biofuels

Researchers from the US Department of Energy (DOE) Joint BioEnergy Institute (JBEI) have developed an ionic liquid (IL)-tolerant bacterial cocktail for the pretreatment of cellulosic biomass at higher temperatures and in the presence of much higher IL concentrations than commercial fungal cocktails.
